2727: Qualify paths in 'add impl members' r=flodiebold a=flodiebold This makes the 'add impl members' assist qualify paths, so that they should resolve to the same thing as in the definition. To do that, it adds an algorithm that finds a path to refer to any item from any module (if possible), which is actually probably the more important part of this PR 😄 It handles visibility, reexports, renamed crates, prelude etc.; I think the only thing that's missing is support for local items. I'm not sure about the performance, since it takes into account every location where the target item has been `pub use`d, and then recursively goes up the module tree; there's probably potential for optimization by memoizing more, but I think the general shape of the algorithm is necessary to handle every case in Rust's module system. ~The 'find path' part is actually pretty complete, I think; I'm still working on the assist (hence the failing tests).~ Fixes #1943.

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
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.
