Igor Matuszewski 406343492c Simplify calculation of missing functions 
Asymptotically computing a set difference is faster but in the average
case we won't have more than ~10 functions. Also prefer not using hash
sets as these may yield nondeterministic results.

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

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 for VS Code setup and the list of features (some of which are VS Code specific).

Debugging

See these instructions on how to debug the vscode extension and the lsp server.
