Florian Diebold 336a3c6121 Fix #3373
Basically, we need to allow variables in the caller self type to unify with the
impl's declared self type. That requires some more contortions in the variable
handling. I'm looking forward to (hopefully) handling this in a cleaner way when
we switch to Chalk's types and unification code.

rust-analyzer logo

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 `rust-analyzer`.
$ 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 are 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.
