2501: Fix coercion from &Foo to an inference variable in a reference r=matklad a=flodiebold We didn't try to unify within the reference, but we should. 2502: Delay legacy macro expansion r=matklad a=edwin0cheng This PR make the following changes: * Delay legacy macro expansion such that we concentrated all item collecting macro expansion in one place. * Add `MacroDirective` to replace 3-tuples * After this refactoring, no macro is expanded recursively, hence we can remove the `MacroStackMonitor` and we handle the expansion limit by the fix-point loop count. 2503: Code: check whether the LSP binary is in PATH r=matklad a=lnicola I'm not really sure about the TS changes. I just made a couple of functions async and it seems to work.

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.
