# Rust Analyzer
[![Build Status](https://travis-ci.org/rust-analyzer/rust-analyzer.svg?branch=master)](https://travis-ci.org/rust-analyzer/rust-analyzer)
Rust Analyzer is an **experimental** modular compiler frontend for the Rust
language. It is a part of a larger rls-2.0 effort to create excellent IDE
support for Rust. If you want to get involved, check the rls-2.0 working group
