# tree-sitter-rust — Rust grammar for tree-sitter

License: permissive · Maintenance: active · Downloads: 10.3M/mo

## What it is and what it does

tree-sitter-rust is a language grammar binding that integrates the Rust language parser into the tree-sitter incremental parsing framework. It allows code to parse Rust source files and work with their syntax trees programmatically. The grammar is derived from the Rust language reference and supports Rust's full syntax.

The package trades initial parse speed for incremental update performance: parsing a file takes roughly two to three times longer than rustc's hand-written parser, but after an edit, tree-sitter can update the existing syntax tree in less than a millisecond. This makes it well-suited for editor integrations, code analysis tools, and language server implementations that need responsive feedback as code changes.

Use it for:

- Build a Rust code editor or IDE plugin that updates syntax highlighting as the user types.
- Analyze Rust codebases to extract syntax tree information for refactoring or code generation.
- Implement a language server with fast incremental parsing for Rust code.
- Parse and transform Rust source code programmatically in analysis pipelines.
- Create syntax-aware code search or navigation tools that understand Rust's grammar.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides a Rust language grammar for tree-sitter, enabling incremental parsing and syntax tree analysis of Rust code.

Yes, if you need to parse Rust code and want incremental parsing performance. The package is actively maintained, has no security vulnerabilities, uses a permissive MIT license, and supports Python >=3.9 on all major platforms. Medium install friction is typical for compiled language bindings. Verify that tree-sitter is available as a peer dependency before installing.

## Install

pip install tree-sitter-rust
uv add tree-sitter-rust
poetry add tree-sitter-rust

## Installing tree-sitter-rust

Before you install: Medium install friction due to compiled wheels, but well-supported across platforms (x86_64, ARM, Windows, macOS, Linux). Active maintenance with recent releases and no known vulnerabilities.

License in practice: MIT license permits unrestricted use, modification, and distribution in both open-source and proprietary projects with minimal attribution requirements.

Quickstart:

pip install tree-sitter-rust

import tree_sitter_rust

Requires Python >=3.9. Requires tree-sitter as a peer dependency (not included in this package's runtime dependencies).

Verify before relying:

- Whether tree-sitter is automatically installed as a transitive dependency or must be installed separately.
- API stability guarantees or semantic versioning policy for the grammar across releases.
- Specific use patterns and integration points with the tree-sitter framework from Python.
