+
+Syn is a parsing library for parsing a stream of Rust tokens into a syntax tree
+of Rust source code.
+
+Currently this library is geared toward use in Rust procedural macros, but
+contains some APIs that may be useful more generally.
+
+- **Data structures** — Syn provides a syntax tree that can represent most
+ stable Rust source code and some unstable syntax. The syntax tree is rooted at
+ [`syn::File`] which represents a full source file, but there are other entry
+ points that may be useful to procedural macros including [`syn::Item`],
+ [`syn::Expr`] and [`syn::Type`].
+
+- **Derives** — Of particular interest to derive macros is [`syn::DeriveInput`]
+ which is any of the three legal input items to a derive macro. An example
+ below shows using this type in a library that can derive implementations of a
+ user-defined trait.
+
+- **Parsing** — Parsing in Syn is built around [parser functions] with the
+ signature `fn(ParseStream) -> Result<T>`. Every syntax tree node defined by
+ Syn is individually parsable and may be used as a building block for custom
+ syntaxes, or you may dream up your own brand new syntax without involving any
+ of our syntax tree types.
+
+- **Location information** — Every token parsed by Syn is associated with a
+ `Span` that tracks line and column information back to the source of that
+ token. These spans allow a procedural macro to display detailed error messages
+ pointing to all the right places in the user's code. There is an example of
+ this below.
+
+- **Feature flags** — Functionality is aggressively feature gated so your
+ procedural macros enable only what they need, and do not pay in compile time
+ for all the rest.
+
+[`syn::File`]: https://docs.rs/syn/3/syn/struct.File.html
+[`syn::Item`]: https://docs.rs/syn/3/syn/enum.Item.html
+[`syn::Expr`]: https://docs.rs/syn/3/syn/enum.Expr.html
+[`syn::Type`]: https://docs.rs/syn/3/syn/enum.Type.html

+
+[*Release notes*](https://github.com/dtolnay/syn/releases)
+
+<br>
+
+## Resources
+
+The best way to learn about procedural macros is by writing some. Consider
+working through [this procedural macro workshop][workshop] to get familiar with
+the different types of procedural macros. The workshop contains relevant links
+into the Syn documentation as you work through each project.
+
+[workshop]: https://github.com/dtolnay/proc-macro-workshop
+
+<br>
+
+## Example of a derive macro
+
+The canonical derive macro using Syn looks like this. We write an ordinary Rust
+function tagged with a `proc_macro_derive` attribute and the name of the trait
+we are deriving. Any time that derive appears in the user's code, the Rust
+compiler passes their data structure as tokens into our macro. We get to execute
+arbitrary Rust code to figure out what to do with those tokens, then hand some
+tokens back to the compiler to compile into the user's crate.
+
+[`TokenStream`]: https://doc.rust-lang.org/proc_macro/struct.TokenStream.html
+
+```toml
+# Cargo.toml
+[package]
+...
+
+[lib]
+proc-macro = true
+
+[dependencies]
+syn = "3"
+quote = "1"
+```
+
+```rust
+use proc_macro::TokenStream;
+use quote::quote;
+use syn::{parse_macro_input, DeriveInput};
+
+#[proc_macro_derive(MyMacro)]
+pub fn my_macro(input: TokenStream) -> TokenStream {
+ // Parse the input tokens into a syntax tree
+ let input = parse_macro_input!(input as DeriveInput);
+
+ // Build the output, possibly using quasi-quotation
+ let expanded = quote! {
+ // ...
+ };
+
+ // Hand the output tokens back to the compiler
+ TokenStream::from(expanded)
+}
+```
+
+The [`heapsize`] example directory shows a complete working implementation of a
+derive macro. The example derives a `HeapSize` trait which computes an estimate
+of the amount of heap memory owned by a value.
+
+[`heapsize`]: examples/heapsize
+
+```rust
+pub trait HeapSize {
+ /// Total number of bytes of heap memory owned by `self`.
+ fn heap_size_of_children(&self) -> usize;
+}
+```
+
+The derive macro allows users to write `#[derive(HeapSize)]` on data structures
+in their program.
+
+```rust
+#[derive(HeapSize)]
+struct Demo<'a, T: ?Sized> {
+ a: Box<T>,
+ b: u8,
+ c: &'a str,
+ d: String,
+}
+```
+
+<br>
+
+## Spans and error reporting
+
+The token-based procedural macro API provides great control over where the
+compiler's error messages are displayed in user code. Consider the error the
+user sees if one of their field types does not implement `HeapSize`.
+
+```rust
+#[derive(HeapSize)]
+struct Broken {
+ ok: String,
+ bad: std::thread::Thread,
+}
+```
+
+By tracking span information all the way through the expansion of a procedural
+macro as shown in the `heapsize` example, token-based macros in Syn are able to
+trigger errors that directly pinpoint the source of the problem.
+
+```console
+error[E0277]: the trait bound `Thread: HeapSize` is not satisfied
+ --> src/main.rs:9:5
+ |
+3 | #[derive(HeapSize)]
+ | -------- required by a bound introduced by this call
+...
+9 | bad: std::thread::Thread,
+ | ^^^^^^^^^^^^^^^^^^^^^^^^ the trait `HeapSize` is not implemented for `Thread`
+ |
+ = help: the following other types implement trait `HeapSize`:
+ &'a T
+ Box<T>
+ Demo<'a, T>
+ String
+ [T]
+ u8
+```
+
+<br>
+
+## Parsing a custom syntax
+
+The [`lazy-static`] example directory shows the implementation of a
+`functionlike!(...)` procedural macro in which the input tokens are parsed using
+Syn's parsing API.
+
+[`lazy-static`]: examples/lazy-static
+
+The example reimplements the popular `lazy_static` crate from crates.io as a
+procedural macro.
+
+```rust
+lazy_static! {
+ static ref USERNAME: Regex = Regex::new("^[a-z0-9_-]{3,16}$").unwrap();
+}
+```
+
+The implementation shows how to trigger custom warnings and error messages on
+the macro input.
+
+```console
+warning: come on, pick a more creative name
+ --> src/main.rs:10:16
+ |
+10 | static ref FOO: String = "lazy_static".to_owned();
+ | ^^^
+```
+
+<br>
+
+## Testing
+
+When testing macros, we often care not just that the macro can be used
+successfully but also that when the macro is provided with invalid input it
+produces maximally helpful error messages. Consider using the [`trybuild`] crate
+to write tests for errors that are emitted by your macro or errors detected by
+the Rust compiler in the expanded code following misuse of the macro. Such tests
+help avoid regressions from later refactors that mistakenly make an error no
+longer trigger or be less helpful than it used to be.
+
+[`trybuild`]: https://github.com/dtolnay/trybuild
+
+<br>
+
+## Debugging
+
+When developing a procedural macro it can be helpful to look at what the
+generated code looks like. Use `cargo rustc -- -Zunstable-options
+-Zunpretty=expanded` or the [`cargo expand`] subcommand.
+
+[`cargo expand`]: https://github.com/dtolnay/cargo-expand
+
+To show the expanded code for some crate that uses your procedural macro, run
+`cargo expand` from that crate. To show the expanded code for one of your own
+test cases, run `cargo expand --test the_test_case` where the last argument is
+the name of the test file without the `.rs` extension.
+
+This write-up by Brandon W Maister discusses debugging in more detail:
+[Debugging Rust's new Custom Derive system][debugging].
+
+[debugging]: https://quodlibetor.github.io/posts/debugging-rusts-new-custom-derive-system/
+
+<br>
+
+## Optional features
+
+Syn puts a lot of functionality behind optional features in order to optimize
+compile time for the most common use cases. The following features are
+available.
+
+- **`derive`** *(enabled by default)* — Data structures for representing the
+ possible input to a derive macro, including structs and enums and types.

+## Proc macro shim
+
+Syn operates on the token representation provided by the [proc-macro2] crate
+from crates.io rather than using the compiler's built in proc-macro crate
+directly. This enables code using Syn to execute outside of the context of a
+procedural macro, such as in unit tests or build.rs, and we avoid needing
+incompatible ecosystems for proc macros vs non-macro use cases.
+
+In general all of your code should be written against proc-macro2 rather than
+proc-macro. The one exception is in the signatures of procedural macro entry
+points, which are required by the language to use `proc_macro::TokenStream`.
+
+The proc-macro2 crate will automatically detect and use the compiler's data
+structures when a procedural macro is active.

+/// Define a type that supports parsing and printing a given identifier as if it
+/// were a keyword.
+///
+/// # Usage
+///
+/// As a convention, it is recommended that this macro be invoked within a
+/// module called `kw` or `keyword` and that the resulting parser be invoked
+/// with a `kw::` or `keyword::` prefix.
+///
+/// ```
+/// mod kw {
+/// syn::custom_keyword!(whatever);
+/// }
+/// ```
+///
+/// The generated syntax tree node supports the following operations just like
+/// any built-in keyword token.
+///
+/// - [Peeking] — `input.peek(kw::whatever)`
+///
+/// - [Parsing] — `input.parse::<kw::whatever>()?`
+///
+/// - [Printing] — `quote!( ... #whatever_token ... )`
+///
+/// - Construction from a [`Span`] — `let whatever_token = kw::whatever(sp)`
+///
+/// - Field access to its span — `let sp = whatever_token.span`
+///
+/// [Peeking]: crate::parse::ParseBuffer::peek
+/// [Parsing]: crate::parse::ParseBuffer::parse
+/// [Printing]: quote::ToTokens
+/// [`Span`]: proc_macro2::Span
+///
+/// # Example
+///
+/// This example parses input that looks like `bool = true` or `str = "value"`.
+/// The key must be either the identifier `bool` or the identifier `str`. If
+/// `bool`, the value may be either `true` or `false`. If `str`, the value may
+/// be any string literal.
+///
+/// The symbols `bool` and `str` are not reserved keywords in Rust so these are
+/// not considered keywords in the `syn::token` module. Like any other
+/// identifier that is not a keyword, these can be declared as custom keywords
+/// by crates that need to use them as such.
+///
+/// ```
+/// use syn::{LitBool, LitStr, Result, Token};

+/// ```

+/// - [Peeking] — `input.peek(LeftRightArrow)`

+/// - [Parsing] — `input.parse::<LeftRightArrow>()?`

+ /// If you can avoid doing this, you should, as it limits the ability to

+ /// whether that was because of a syntax error and the user meant to provide
+ /// an `A`, or that the `A`s are finished and it's time to start parsing
+ /// `B`s. Use with care.
+ ///
+ /// Also note that if `A` is a subset of `B`, `A* B*` can be parsed by
+ /// parsing `B*` and removing the leading members of `A` from the
+ /// repetition, bypassing the need to involve the downsides associated with
+ /// speculative parsing.

+ /// [`ParseStream::fork`]: ParseBuffer::fork
+ ///
+ /// # Example
+ ///
+ /// There has been chatter about the possibility of making the colons in the
+ /// turbofish syntax like `path::to::<T>` no longer required by accepting
+ /// `path::to<T>` in expression position. Specifically, according to [RFC
+ /// 2544], [`PathSegment`] parsing should always try to consume a following
+ /// `<` token as the start of generic arguments, and reset to the `<` if
+ /// that fails (e.g. the token is acting as a less-than operator).
+ ///
+ /// This is the exact kind of parsing behavior which requires the "fork,
+ /// try, commit" behavior that [`ParseStream::fork`] discourages. With
+ /// `advance_to`, we can avoid having to parse the speculatively parsed
+ /// content a second time.

+ /// # Drawbacks
+ ///
+ /// The main drawback of this style of speculative parsing is in error
+ /// presentation. Even if the lookahead is the "correct" parse, the error
+ /// that is shown is that of the "fallback" parse. To use the same example
+ /// as the turbofish above, take the following unfinished "turbofish":
+ ///
+ /// ```text
+ /// let _ = f<&'a fn(), for<'a> serde::>();
+ /// ```
+ ///
+ /// If this is parsed as generic arguments, we can provide the error message
+ ///
+ /// ```text
+ /// error: expected identifier
+ /// --> src.rs:L:C
+ /// |
+ /// L | let _ = f<&'a fn(), for<'a> serde::>();
+ /// | ^
+ /// ```
+ ///
+ /// but if parsed using the above speculative parsing, it falls back to
+ /// assuming that the `<` is a less-than when it fails to parse the generic
+ /// arguments, and tries to interpret the `&'a` as the start of a labelled
+ /// loop, resulting in the much less helpful error
+ ///
+ /// ```text
+ /// error: expected `:`
+ /// --> src.rs:L:C
+ /// |
+ /// L | let _ = f<&'a fn(), for<'a> serde::>();
+ /// | ^^
+ /// ```
+ ///
+ /// This can be mitigated with various heuristics (two examples: show both
+ /// forks' parse errors, or show the one that consumed more tokens), but
+ /// when you can control the grammar, sticking to something that can be
+ /// parsed LL(3) and without the LL(*) speculative parsing this makes

+//!
+//! <br>
+//!
+//! Syn is a parsing library for parsing a stream of Rust tokens into a syntax
+//! tree of Rust source code.
+//!
+//! Currently this library is geared toward use in Rust procedural macros, but
+//! contains some APIs that may be useful more generally.
+//!
+//! - **Data structures** — Syn provides a syntax tree that can represent most
+//! stable Rust source code and some unstable syntax. The syntax tree is
+//! rooted at [`syn::File`] which represents a full source file, but there are
+//! other entry points that may be useful to procedural macros including
+//! [`syn::Item`], [`syn::Expr`] and [`syn::Type`].
+//!
+//! - **Derives** — Of particular interest to derive macros is
+//! [`syn::DeriveInput`] which is any of the three legal input items to a
+//! derive macro. An example below shows using this type in a library that can
+//! derive implementations of a user-defined trait.
+//!
+//! - **Parsing** — Parsing in Syn is built around [parser functions] with the
+//! signature `fn(ParseStream) -> Result<T>`. Every syntax tree node defined
+//! by Syn is individually parsable and may be used as a building block for
+//! custom syntaxes, or you may dream up your own brand new syntax without
+//! involving any of our syntax tree types.
+//!
+//! - **Location information** — Every token parsed by Syn is associated with a
+//! `Span` that tracks line and column information back to the source of that
+//! token. These spans allow a procedural macro to display detailed error
+//! messages pointing to all the right places in the user's code. There is an
+//! example of this below.
+//!
+//! - **Feature flags** — Functionality is aggressively feature gated so your
+//! procedural macros enable only what they need, and do not pay in compile
+//! time for all the rest.
+//!
+//! [`syn::File`]: File
+//! [`syn::Item`]: Item
+//! [`syn::Expr`]: Expr
+//! [`syn::Type`]: Type
+//! [`syn::DeriveInput`]: DeriveInput
+//! [parser functions]: mod@parse
+//!
+//! <br>
+//!
+//! # Example of a derive macro
+//!
+//! The canonical derive macro using Syn looks like this. We write an ordinary
+//! Rust function tagged with a `proc_macro_derive` attribute and the name of
+//! the trait we are deriving. Any time that derive appears in the user's code,
+//! the Rust compiler passes their data structure as tokens into our macro. We
+//! get to execute arbitrary Rust code to figure out what to do with those
+//! tokens, then hand some tokens back to the compiler to compile into the
+//! user's crate.
+//!
+//! [`TokenStream`]: proc_macro::TokenStream
+//!
+//! ```toml
+//! # Cargo.toml
+//! [package]
+//! ...
+//!
+//! [lib]
+//! proc-macro = true
+//!
+//! [dependencies]
+//! syn = "3"
+//! quote = "1"
+//! ```
+//!
+//! ```
+//! # extern crate proc_macro;
+//! #
+//! use proc_macro::TokenStream;
+//! use quote::quote;
+//! use syn::{parse_macro_input, DeriveInput};
+//!
+//! # const IGNORE_TOKENS: &str = stringify! {
+//! #[proc_macro_derive(MyMacro)]
+//! # };
+//! pub fn my_macro(input: TokenStream) -> TokenStream {
+//! // Parse the input tokens into a syntax tree
+//! let input = parse_macro_input!(input as DeriveInput);
+//!
+//! // Build the output, possibly using quasi-quotation
+//! let expanded = quote! {
+//! // ...
+//! };
+//!
+//! // Hand the output tokens back to the compiler
+//! TokenStream::from(expanded)
+//! }
+//! ```
+//!
+//! The [`heapsize`] example directory shows a complete working implementation
+//! of a derive macro. The example derives a `HeapSize` trait which computes an
+//! estimate of the amount of heap memory owned by a value.
+//!
+//! [`heapsize`]: https://github.com/dtolnay/syn/tree/master/examples/heapsize
+//!
+//! ```
+//! pub trait HeapSize {
+//! /// Total number of bytes of heap memory owned by `self`.
+//! fn heap_size_of_children(&self) -> usize;
+//! }
+//! ```
+//!
+//! The derive macro allows users to write `#[derive(HeapSize)]` on data
+//! structures in their program.
+//!
+//! ```
+//! # const IGNORE_TOKENS: &str = stringify! {
+//! #[derive(HeapSize)]
+//! # };
+//! struct Demo<'a, T: ?Sized> {
+//! a: Box<T>,
+//! b: u8,
+//! c: &'a str,
+//! d: String,
+//! }
+//! ```
+//!
+//! <p><br></p>
+//!
+//! # Spans and error reporting
+//!
+//! The token-based procedural macro API provides great control over where the
+//! compiler's error messages are displayed in user code. Consider the error the
+//! user sees if one of their field types does not implement `HeapSize`.
+//!
+//! ```
+//! # const IGNORE_TOKENS: &str = stringify! {
+//! #[derive(HeapSize)]
+//! # };
+//! struct Broken {
+//! ok: String,
+//! bad: std::thread::Thread,
+//! }
+//! ```
+//!
+//! By tracking span information all the way through the expansion of a
+//! procedural macro as shown in the `heapsize` example, token-based macros in
+//! Syn are able to trigger errors that directly pinpoint the source of the
+//! problem.
+//!
+//! ```text
+//! error[E0277]: the trait bound `Thread: HeapSize` is not satisfied
+//! --> src/main.rs:9:5
+//! |
+//! 3 | #[derive(HeapSize)]
+//! | -------- required by a bound introduced by this call
+//! ...
+//! 9 | bad: std::thread::Thread,
+//! | ^^^^^^^^^^^^^^^^^^^^^^^^ the trait `HeapSize` is not implemented for `Thread`
+//! |
+//! = help: the following other types implement trait `HeapSize`:
+//! &'a T
+//! Box<T>
+//! Demo<'a, T>
+//! String
+//! [T]
+//! u8
+//! ```
+//!
+//! <br>
+//!
+//! # Parsing a custom syntax
+//!
+//! The [`lazy-static`] example directory shows the implementation of a
+//! `functionlike!(...)` procedural macro in which the input tokens are parsed
+//! using Syn's parsing API.
+//!
+//! [`lazy-static`]: https://github.com/dtolnay/syn/tree/master/examples/lazy-static
+//!
+//! The example reimplements the popular `lazy_static` crate from crates.io as a
+//! procedural macro.
+//!
+//! ```
+//! # macro_rules! lazy_static {
+//! # ($($tt:tt)*) => {}
+//! # }
+//! #
+//! lazy_static! {
+//! static ref USERNAME: Regex = Regex::new("^[a-z0-9_-]{3,16}$").unwrap();
+//! }
+//! ```
+//!
+//! The implementation shows how to trigger custom warnings and error messages
+//! on the macro input.
+//!
+//! ```text
+//! warning: come on, pick a more creative name
+//! --> src/main.rs:10:16
+//! |
+//! 10 | static ref FOO: String = "lazy_static".to_owned();
+//! | ^^^
+//! ```
+//!
+//! <br>
+//!
+//! # Testing
+//!
+//! When testing macros, we often care not just that the macro can be used
+//! successfully but also that when the macro is provided with invalid input it
+//! produces maximally helpful error messages. Consider using the [`trybuild`]
+//! crate to write tests for errors that are emitted by your macro or errors
+//! detected by the Rust compiler in the expanded code following misuse of the
+//! macro. Such tests help avoid regressions from later refactors that
+//! mistakenly make an error no longer trigger or be less helpful than it used
+//! to be.
+//!
+//! [`trybuild`]: https://github.com/dtolnay/trybuild
+//!
+//! <br>
+//!
+//! # Debugging
+//!
+//! When developing a procedural macro it can be helpful to look at what the
+//! generated code looks like. Use `cargo rustc -- -Zunstable-options

+//! # Optional features
+//!
+//! Syn puts a lot of functionality behind optional features in order to
+//! optimize compile time for the most common use cases. The following features
+//! are available.
+//!
+//! - **`derive`** *(enabled by default)* — Data structures for representing the
+//! possible input to a derive macro, including structs and enums and types.
+//! - **`full`** — Data structures for representing the syntax tree of all valid
+//! Rust source code, including items and expressions.
+//! - **`parsing`** *(enabled by default)* — Ability to parse input tokens into
+//! a syntax tree node of a chosen type.
+//! - **`printing`** *(enabled by default)* — Ability to print a syntax tree
+//! node as tokens of Rust source code.
+//! - **`visit`** — Trait for traversing a syntax tree.
+//! - **`visit-mut`** — Trait for traversing and mutating in place a syntax
+//! tree.
+//! - **`fold`** — Trait for transforming an owned syntax tree.
+//! - **`clone-impls`** *(enabled by default)* — Clone impls for all syntax tree
+//! types.
+//! - **`extra-traits`** — Debug, Eq, PartialEq, Hash impls for all syntax tree
+//! types.
+//! - **`proc-macro`** *(enabled by default)* — Runtime dependency on the
+//! dynamic library libproc_macro from rustc toolchain.
+//!
+//! <br>
+//!
+//! # Compatibility notes
+//!
+//! Syn is able to accommodate most kinds of Rust grammar changes without a new
+//! major release through the following mechanisms.
+//!
+//! #### Modifiers
+//!
+//! Syntax tree structs which are expected to grow over the course of future
+//! releases of the Rust language, such as [`ItemTrait`], contain a `modifiers`
+//! field of one of several "Modifiers" types, in that case [`TraitModifiers`].
+//!
+//! All modifiers structs have the following commonalities:
+//!
+//! - Type name ending with "Modifiers".
+//!
+//! - Implements [`Default`]. The default value is guaranteed to comprise no
+//! tokens.
+//!
+//! - Non-exhaustive. Can only be instantiated by Syn's parser or by creating
+//! and then mutating an empty default value.
+//!
+//! - Does not implement [`Parse`][parse::Parse]. When parsing, they are parsed
+//! by the enclosing syntax tree node.
+//!
+//! - Does not implement [`ToTokens`][quote::ToTokens]. In some cases the syntax
+//! that might be held in modifiers in the future is not necessarily
+//! contiguous tokens.
+//!
+//! - Provides `.require_empty() -> Result<()>` which returns a meaningfully
+//! spanned error if the modifiers are different from the empty default. This
+//! enables a caller to reject syntax it does not recognize without knowing
+//! what that syntax may be.
+//!
+//! Across major versions, fields may be promoted out of a "Modifiers" struct
+//! into the enclosing syntax tree node(s), typically for syntax that has
+//! already been incorporated into a stable release of Rust or is deemed
+//! sufficiently on track for stabilization.
+//!
+//! #### Verbatim variants
+//!
+//! Syntax tree enums which are expected to grow over the course of future
+//! releases of the Rust language are declared non-exhaustive and may contain a
+//! variant named `Verbatim` that holds [`TokenStream`]. For example
+//! [`Expr::Verbatim`].
+//!
+//! Unstable language syntax for which a dedicated syntax tree node does not yet
+//! exist will get parsed to `Verbatim`, thus allowing unstable syntax to
+//! round-trip through parsing and printing of a syntax tree. For example you
+//! might parse token input to [`ItemTrait`] (a trait definition) in order to
+//! read or modify its method signatures, or insert associated types, or insert
+//! default function bodies. All of this would work even if there is some
+//! `Expr::Verbatim` syntax somewhere in one of the function bodies in the macro
+//! input.
+//!
+//! Verbatim variants are not intended to be constructed other than by Syn's
+//! parser. Do not rely on passing one containing arbitrary tokens through Syn's
+//! `ToTokens` implementations or through any other library, as it may panic or
+//! otherwise misbehave, such as failing to accurately parenthesize
+//! subexpressions to preserve precedence.
+//!
+//! It is important not to write code that expects Syn's parser to continue to
+//! produce `Verbatim` when parsing some particular syntax construct, as that
+//! behavior changes across patch releases of Syn. Patch releases can promote
+//! something that used to be parsed as `Verbatim` into a new dedicated syntax
+//! tree node. Verbatim variants are specifically only for round-tripping code
+//! not acted on by the caller.
+//!
+//! #### Non-exhaustive enums
+//!
+//! Some enums in the syntax tree are declared #\[non_exhaustive\] and cannot
+//! be pattern-matched using an exhaustive match; a default case (`_ => ...`) is
+//! required. New variants of these enums will be added over time corresponding
+//! to new Rust syntax.
+//!
+//! For testing the exhaustiveness of a match on such an enum in downstream
+//! code, it is recommended to use the following idiom.
+//!
+//! ```
+//! # use syn::Expr;
+//! #
+//! # fn example(expr: Expr) {
+//! match expr {
+//! #![cfg_attr(test, deny(non_exhaustive_omitted_patterns))]
+//!
+//! Expr::Array(expr) => { /*...*/ }
+//! Expr::Assign(expr) => { /*...*/ }
+#![cfg_attr(not(doctest), doc = " ...")]
+//! Expr::Yield(expr) => { /*...*/ }
+//!
+//! _ => { /* some sane fallback */ }
+//! }
+//! # }
+//! ```
+//!
+//! This way you will be notified by a test failure when a variant is added, so
+//! that you can add code to handle it, but your library will continue to
+//! compile and work for downstream users in the interim.

+/// Types that can be parsed by looking at just one token.

+/// [`ParseStream::peek`]: crate::parse::ParseBuffer::peek
+pub trait Peek: Sealed {
+ // Not public API.
+ #[doc(hidden)]
+ type Token: Token;
+}
+
+/// Pseudo-token used for peeking the end of a parse stream.
+///
+/// This type is only useful as an argument to one of the following functions:
+///
+/// - [`ParseStream::peek`][crate::parse::ParseBuffer::peek]
+/// - [`ParseStream::peek2`][crate::parse::ParseBuffer::peek2]
+/// - [`ParseStream::peek3`][crate::parse::ParseBuffer::peek3]
+/// - [`Lookahead1::peek`]
+///
+/// The peek will return `true` if there are no remaining tokens after that
+/// point in the parse stream.
+///
+/// # Example
+///
+/// Suppose we are parsing attributes containing core::fmt inspired formatting
+/// arguments:
+///
+/// - `#[fmt("simple example")]`
+/// - `#[fmt("interpolation e{}ample", self.x)]`
+/// - `#[fmt("interpolation e{x}ample")]`
+///
+/// and we want to recognize the cases where no interpolation occurs so that
+/// more efficient code can be generated.
+///
+/// The following implementation uses `input.peek(Token![,]) &&
+/// input.peek2(End)` to recognize the case of a trailing comma without
+/// consuming the comma from the parse stream, because if it isn't a trailing
+/// comma, that same comma needs to be parsed as part of `args`.
+///
+/// ```
+/// use proc_macro2::TokenStream;
+/// use quote::quote;
+/// use syn::parse::{End, Parse, ParseStream, Result};
+/// use syn::{parse_quote, Attribute, LitStr, Token};
+///
+/// struct FormatArgs {
+/// template: LitStr, // "...{}..."
+/// args: TokenStream, // , self.x
+/// }
+///
+/// impl Parse for FormatArgs {
+/// fn parse(input: ParseStream) -> Result<Self> {
+/// let template: LitStr = input.parse()?;
+///
+/// let args = if input.is_empty()
+/// || input.peek(Token![,]) && input.peek2(End)
+/// {
+/// input.parse::<Option<Token![,]>>()?;
+/// TokenStream::new()
+/// } else {
+/// input.parse()?
+/// };
+///
+/// Ok(FormatArgs {
+/// template,
+/// args,
+/// })
+/// }
+/// }
+///
+/// fn main() -> Result<()> {
+/// let attrs: Vec<Attribute> = parse_quote! {
+/// #[fmt("simple example")]
+/// #[fmt("interpolation e{}ample", self.x)]
+/// #[fmt("interpolation e{x}ample")]
+/// };
+///
+/// for attr in &attrs {
+/// let FormatArgs { template, args } = attr.parse_args()?;
+/// let requires_fmt_machinery =
+/// !args.is_empty() || template.value().contains(['{', '}']);
+/// let out = if requires_fmt_machinery {
+/// quote! {

+/// quote! {
+/// __formatter.write_str(#template)
+/// }
+/// };
+/// println!("{}", out);
+/// }
+/// Ok(())
+/// }
+/// ```
+///
+/// Implementing this parsing logic without `peek2(End)` is more clumsy because
+/// we'd need a parse stream actually advanced past the comma before being able
+/// to find out whether there is anything after it. It would look something
+/// like:
+///
+/// ```
+/// # use proc_macro2::TokenStream;

+//! Parsing interface for parsing a token stream into a syntax tree node.
+//!
+//! Parsing in Syn is built on parser functions that take in a [`ParseStream`]
+//! and produce a [`Result<T>`] where `T` is some syntax tree node. Underlying
+//! these parser functions is a lower level mechanism built around the
+//! [`Cursor`] type. `Cursor` is a cheaply copyable cursor over a range of
+//! tokens in a token stream.
+//!
+//! [`Result<T>`]: Result
+//! [`Cursor`]: crate::buffer::Cursor
+//!
+//! # Example
+//!
+//! Here is a snippet of parsing code to get a feel for the style of the
+//! library. We define data structures for a subset of Rust syntax including
+//! enums (not shown) and structs, then provide implementations of the [`Parse`]
+//! trait to parse these syntax tree data structures from a token stream.
+//!
+//! Once `Parse` impls have been defined, they can be called conveniently from a
+//! procedural macro through [`parse_macro_input!`] as shown at the bottom of
+//! the snippet. If the caller provides syntactically invalid input to the
+//! procedural macro, they will receive a helpful compiler error message
+//! pointing out the exact token that triggered the failure to parse.
+//!
+//! [`parse_macro_input!`]: crate::parse_macro_input!
+//!
+//! ```
+//! # extern crate proc_macro;

+//! use proc_macro::TokenStream;

+//!
+//! # The `syn::parse*` functions
+//!
+//! The [`syn::parse`], [`syn::parse2`], and [`syn::parse_str`] functions serve
+//! as an entry point for parsing syntax tree nodes that can be parsed in an
+//! obvious default way. These functions can return any syntax tree node that
+//! implements the [`Parse`] trait, which includes most types in Syn.
+//!
+//! [`syn::parse`]: crate::parse()
+//! [`syn::parse2`]: crate::parse2()
+//! [`syn::parse_str`]: crate::parse_str()
+//!

+//! #
+//! # run_parser().unwrap();
+//! ```
+//!
+//! The [`parse_quote!`] macro also uses this approach.
+//!
+//! [`parse_quote!`]: crate::parse_quote!
+//!
+//! # The `Parser` trait
+//!
+//! Some types can be parsed in several ways depending on context. For example
+//! an [`Attribute`] can be either "outer" like `#[...]` or "inner" like
+//! `#![...]` and parsing the wrong one would be a bug. Similarly [`Punctuated`]
+//! may or may not allow trailing punctuation, and parsing it the wrong way
+//! would either reject valid input or accept invalid input.
+//!
+//! [`Attribute`]: crate::Attribute
+//! [`Punctuated`]: crate::punctuated
+//!
+//! The `Parse` trait is not implemented in these cases because there is no good
+//! behavior to consider the default.
+//!
+//! ```compile_fail
+//! # extern crate proc_macro;
+//! #
+//! # use syn::punctuated::Punctuated;
+//! # use syn::{PathSegment, Result, Token};
+//! #
+//! # fn f(tokens: proc_macro::TokenStream) -> Result<()> {
+//! #
+//! // Can't parse `Punctuated` without knowing whether trailing punctuation
+//! // should be allowed in this context.
+//! let path: Punctuated<PathSegment, Token![::]> = syn::parse(tokens)?;
+//! #
+//! # Ok(())
+//! # }
+//! ```
+//!
+//! In these cases the types provide a choice of parser functions rather than a
+//! single `Parse` implementation, and those parser functions can be invoked
+//! through the [`Parser`] trait.
+//!
+//!
+//! ```
+//! # extern crate proc_macro;
+//! #
+//! use proc_macro::TokenStream;
+//! use syn::parse::Parser;

+//! - The fields of a struct are `Punctuated<Field, Token![,]>`.
+//! - The segments of a path are `Punctuated<PathSegment, Token![::]>`.
+//! - The bounds on a generic parameter are `Punctuated<TypeParamBound,
+//! Token![+]>`.
+//! - The arguments to a function call are `Punctuated<Expr, Token![,]>`.
+//!
+//! This module provides a common representation for these punctuated sequences
+//! in the form of the [`Punctuated<T, P>`] type. We store a vector of pairs of
+//! syntax tree node + punctuation, where every node in the sequence is followed
+//! by punctuation except for possibly the final one.
+//!
+//! [`Punctuated<T, P>`]: Punctuated
+//!
+//! ```text
+//! a_function_call(arg1, arg2, arg3);

+//! A trait that can provide the `Span` of the complete contents of a syntax
+//! tree node.
+//!
+//! <br>
+//!
+//! # Example
+//!
+//! Suppose in a procedural macro we have a [`Type`] that we want to assert
+//! implements the [`Sync`] trait. Maybe this is the type of one of the fields
+//! of a struct for which we are deriving a trait implementation, and we need to
+//! be able to pass a reference to one of those fields across threads.
+//!
+//! [`Type`]: crate::Type
+//! [`Sync`]: core::marker::Sync
+//!
+//! If the field type does *not* implement `Sync` as required, we want the
+//! compiler to report an error pointing out exactly which type it was.
+//!
+//! The following macro code takes a variable `ty` of type `Type` and produces a
+//! static assertion that `Sync` is implemented for that type.
+//!
+//! ```
+//! # extern crate proc_macro;
+//! #
+//! use proc_macro::TokenStream;
+//! use proc_macro2::Span;
+//! use quote::quote_spanned;
+//! use syn::Type;
+//! use syn::spanned::Spanned;
+//!
+//! # const IGNORE_TOKENS: &str = stringify! {
+//! #[proc_macro_derive(MyMacro)]
+//! # };
+//! pub fn my_macro(input: TokenStream) -> TokenStream {
+//! # let ty = get_a_type();
+//! /* ... */
+//!
+//! let assert_sync = quote_spanned! {ty.span()=>
+//! struct _AssertSync where #ty: Sync;
+//! };
+//!
+//! /* ... */
+//! # input
+//! }
+//! #
+//! # fn get_a_type() -> Type {
+//! # unimplemented!()
+//! # }
+//! ```
+//!
+//! By inserting this `assert_sync` fragment into the output code generated by
+//! our macro, the user's code will fail to compile if `ty` does not implement
+//! `Sync`. The errors they would see look like the following.
+//!
+//! ```text
+//! error[E0277]: the trait bound `*const i32: core::marker::Sync` is not satisfied
+//! --> src/main.rs:10:21
+//! |
+//! 10 | bad_field: *const i32,
+//! | ^^^^^^^^^^ `*const i32` cannot be shared between threads safely
+//! ```
+//!
+//! In this technique, using the `Type`'s span for the error message makes the
+//! error appear in the correct place underlining the right type.
+//!
+//! <br>
+//!
+//! # Limitations
+//!
+//! The underlying [`proc_macro::Span::join`] method is nightly-only. When
+//! called from within a procedural macro in a nightly compiler, `Spanned` will
+//! use `join` to produce the intended span. When not using a nightly compiler,
+//! only the span of the *first token* of the syntax tree node is returned.
+//!
+//! In the common case of wanting to use the joined span as the span of a
+//! `syn::Error`, consider instead using [`syn::Error::new_spanned`] which is
+//! able to span the error correctly under the complete syntax tree node without
+//! needing the unstable `join`.
+//!
+//! [`syn::Error::new_spanned`]: crate::Error::new_spanned

+//! Tokens representing Rust punctuation, keywords, and delimiters.
+//!
+//! The type names in this module can be difficult to keep straight, so we
+//! prefer to use the [`Token!`] macro instead. This is a type-macro that
+//! expands to the token type of the given token.
+//!
+//! [`Token!`]: crate::Token
+//!
+//! # Example
+//!
+//! The [`ItemStatic`] syntax tree node is defined like this.
+//!
+//! [`ItemStatic`]: crate::ItemStatic
+//!
+//! ```
+//! # use syn::{Attribute, Expr, Ident, Token, Type, Visibility};
+//! #
+//! pub struct ItemStatic {
+//! pub attrs: Vec<Attribute>,
+//! pub vis: Visibility,
+//! pub static_token: Token![static],
+//! pub mutability: Option<Token![mut]>,
+//! pub ident: Ident,
+//! pub colon_token: Token![:],
+//! pub ty: Box<Type>,
+//! pub eq_token: Token![=],
+//! pub expr: Box<Expr>,
+//! pub semi_token: Token![;],
+//! }
+//! ```
+//!
+//! # Parsing
+//!
+//! Keywords and punctuation can be parsed through the [`ParseStream::parse`]
+//! method. Delimiter tokens are parsed using the [`parenthesized!`],
+//! [`bracketed!`] and [`braced!`] macros.
+//!
+//! [`ParseStream::parse`]: crate::parse::ParseBuffer::parse()
+//! [`parenthesized!`]: crate::parenthesized!
+//! [`bracketed!`]: crate::bracketed!
+//! [`braced!`]: crate::braced!
+//!
+//! ```
+//! use syn::{Attribute, Result};
+//! use syn::parse::{Parse, ParseStream};
+//! #
+//! # enum ItemStatic {}
+//!
+//! // Parse the ItemStatic struct shown above.
+//! impl Parse for ItemStatic {
+//! fn parse(input: ParseStream) -> Result<Self> {
+//! # use syn::ItemStatic;
+//! # fn parse(input: ParseStream) -> Result<ItemStatic> {
+//! Ok(ItemStatic {
+//! attrs: input.call(Attribute::parse_outer)?,
+//! vis: input.parse()?,
+//! static_token: input.parse()?,
+//! mutability: input.parse()?,
+//! ident: input.parse()?,
+//! colon_token: input.parse()?,
+//! ty: input.parse()?,
+//! eq_token: input.parse()?,
+//! expr: input.parse()?,
+//! semi_token: input.parse()?,
+//! })
+//! # }
+//! # unimplemented!()
+//! }
+//! }
+//! ```
+//!
+//! # Other operations
+//!
+//! Every keyword and punctuation token supports the following operations.
+//!
+//! - [Peeking] — `input.peek(Token![...])`
+//!
+//! - [Parsing] — `input.parse::<Token![...]>()?`
+//!
+//! - [Printing] — `quote!( ... #the_token ... )`
+//!
+//! - Construction from a [`Span`] — `let the_token = Token`
+//!
+//! - Field access to its span — `let sp = the_token.span`
+//!
+//! [Peeking]: crate::parse::ParseBuffer::peek()
+//! [Parsing]: crate::parse::ParseBuffer::parse()
+//! [Printing]: https://docs.rs/quote/1.0/quote/trait.ToTokens.html

+/// This is an internal helper used to safely convert a heap-allocated byte buffer

+///
+/// ### Why this is needed
+///
+/// Reconstructing a `Box<T>` is tricky because:
+/// 1. **Provenance**: If we derive the pointer from a temporary shared reference (e.g., `&[u8]`),
+/// Miri/Stacked Borrows will tag the pointer as `SharedReadOnly`. Reclaiming unique ownership
+/// and deallocating through a pointer with shared provenance is Undefined Behavior. To avoid this,
+/// we must derive the final pointer directly from `Box::into_raw` (which carries `Unique` provenance).
+/// 2. **DST Metadata**: Unsized types (like `VarTupleULE`) may have custom metadata that is *not*
+/// simply the byte length of the allocation. We must use `T::from_bytes_unchecked` to construct
+/// a reference with the correct metadata, and then combine that metadata with the unique thin
+/// pointer from `Box::into_raw` without clobbering the provenance.
+///
+/// ### Safety
+///
+/// - `T::from_bytes_unchecked` must be safe to call on the slice behind bytes
