Rust grammar for [tree-sitter](https://github.com/tree-sitter/tree-sitter).

## Features

- **Speed** — When initially parsing a file, `tree-sitter-rust` takes around two to three times

  as long as rustc's hand-written parser.

  ```sh

  $ wc -l examples/ast.rs

    2157 examples/ast.rs

  $ rustc -Z unpretty=ast-tree -Z time-passes examples/ast.rs | head -n0

    time:   0.002; rss:   55MB ->   60MB (   +5MB)  parse_crate

  $ tree-sitter parse examples/ast.rs --quiet --time

    examples/ast.rs    6.48 ms        9908 bytes/ms

  ```

  But if you _edit_ the file after parsing it, tree-sitter can generally _update_

  the previous existing syntax tree to reflect your edit in less than a millisecond,

  thanks to its incremental parsing system.

- [The Rust Reference](https://doc.rust-lang.org/reference/) — While Rust does

  not have a specification, the reference tries to describe its working in detail.

  It tends to be out of date.
