Aleksey Kladov 0ee5bd16c9 cancel salsa's validation
This small fix should improve rust-analyzer resopnsivness for
real-time operations like onEnter handling.

Turns out, salsa's validation can take hundreds of milliseconds, and,
in case no changes were made, it won't be triggering any queries.

Because we check for cancellation in queries, that means that
validation is not cancellable!

What this PR does is injecting check_canceled checks into validation,
by using salsa's event API, which wasn't meant to be used like this,
but, hey, it works!

Here's the onEnter handling before and after this change:

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

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 (code should be in path)

For setup for other editors, see ./docs/user.

# 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 install-code

# alternatively, install only the server. Binary name is `ra_lsp_server`.
$ cargo install-lsp

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.
