Package Exports

tree-sitter-rust
tree-sitter-rust/bindings/node/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (tree-sitter-rust) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

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.
