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:

Language Server Quick Start

rust-analyzer is a work-in-progress, so 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 the language server itself
• latest stable npm and VS Code for VS Code extension

To quickly install the rust-analyzer language server and VS Code extension with standard setup (code and cargo in $PATH, etc), use this:

# 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 xtask install

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

For non-standard setup of VS Code and other editors, or if the language server cannot start, see ./docs/user.
