Merge #2523 
2523: Fixed #2250 r=matklad a=gab-umich

Bugfix Debriefing:

1. Tuple in type annotation expands correctly;
2. Expansion will prefer the following delimiter when possible. This involves modification of previous test cases to match current behaviour. 
3. New regression tests added to verify the consistency between tuple expansion in type annotation and tuple expansion in rvalue. Both should behave exactly the same.

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 the rls-2.0 working group in the compiler-team repository:

https://github.com/rust-lang/compiler-team/tree/master/content/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

To quickly install rust-analyzer with 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.

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.
