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
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 for VS Code setup and the list of features (some of which are VS Code specific).
See these instructions on how to debug the vscode extension and the lsp server.
