Rust grammar for tree-sitter

Features

  • Speed — When initially parsing a file, tree-sitter-rust takes around twice as long as Rustc's hand-coded parser.

    $ wc -l examples/ast.rs
      2157 examples/ast.rs
    
    $ rustc -Z ast-json-noexpand -Z time-passes examples/ast.rs | head -n1
      time: 0.007    parsing # (7 ms)
    
    $ tree-sitter parse examples/ast.rs --quiet --time
      examples/ast.rs    16 ms

    But if you edit the file after parsing it, this parser can generally update the previous existing syntax tree to reflect your edit in less than a millisecond, thanks to Tree-sitter's incremental parsing system.
