Rust Analyzer

Build Status

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 in the compiler-team repository:

https://github.com/rust-lang/compiler-team/tree/master/working-groups/rls-2.0

Work on the Rust Analyzer is sponsored by

Ferrous Systems

Language Server Quick Start

Rust Analyzer is a work-in-progress, so you'll have to build it from source, and you might encounter critical bugs. That said, it is complete enough to provide a useful IDE experience and some people use it as a daily driver.

To build rust-analyzer, you need:

  • latest stable rust for language server itself
  • latest stable npm and VS Code for VS Code extension (code should be in path)

For setup for other editors, see ./docs/user.

# clone the repo
$ git clone https://github.com/rust-analyzer/rust-analyzer && cd rust-analyzer

# install both the language server and VS Code extension
$ cargo install-code

# alternatively, install only the server. Binary name is `ra_lsp_server`.
$ cargo install-lsp

Documentation

If you want to contribute to rust-analyzer or just curious about how things work under the hood, check the ./docs/dev folder.

If you want to use rust-analyzer's language server with your editor of choice, check ./docs/user folder. It also contains some tips & tricks to help you be more productive when using rust-analyzer.
