# Rust Analyzer
|

[](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 rls-2.0 working group repository:
|
|
|
|
https://github.com/rust-analyzer/WG-rls2.0
|
|
|
|
Work on the Rust Analyzer is sponsored by

|
|
|
|
## Quick Start
|
|
|
|
Rust analyzer builds on Rust >= 1.31.0 and uses the 2018 edition.
|
|
|
|
```
|
|
# run tests
|
|
$ cargo test
|
|
|
|
# show syntax tree of a Rust file
|
|
$ cargo run --package ra_cli parse < crates/ra_syntax/src/lib.rs
|
|
|
|
# show symbols of a Rust file
|
|
$ cargo run --package ra_cli symbols < crates/ra_syntax/src/lib.rs
|
|
|
|
# install the language server
|
|
$ cargo install-lsp
|
|
or
|
|
$ cargo install --path crates/ra_lsp_server
|
|
```
|
|
|
|
See [these instructions](./editors/README.md) for VS Code setup and the list of
|
|
features (some of which are VS Code specific).
