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 complete syntax tree that can -//! represent any valid Rust source code. 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 -//! [dependencies] -//! syn = "2.0" -//! quote = "1.0" -//! -//! [lib] -//! proc-macro = true -//! ``` -//! -//! ``` -//! # 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 `std::thread::Thread: HeapSize` is not satisfied -//! --> src/main.rs:7:5 -//! | -//! 7 | bad: std::thread::Thread, -//! | ^^^^^^^^^^^^^^^^^^^^^^^^ the trait `HeapSize` is not implemented for `Thread` -//! ``` -//! -//! <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. -//! -//!
