Announcements: Client Changes

[matklad]

This issue exists to announce changes which might affect rust-analyzer plugins for different editors.
If you maintain such a plugin, consider subscribing to this issue.

All our protocol extensions are documented at lsp-extensions.md. I'll try to remember to leave a comment on this issue if I modify that file.

After #4632, all our current extensions are documented. There were a bunch of minor changes here and there. Most notably some requests were moved from rust-analyzer/foo to experimental/foo, in hope that this might be useful for other servers, and to mark the extensions we intend to upstream to the protocol itself.

Notably, inlay hints and runnables are are still unchanged: i want to upstream these two as well, but I am not too happy with their current state, and I don't have time to polish them right now. So i opted for documenting them as is, and cleaning up later.

#4688 documents our initilizationOptions.

#4710 changes API for runnables. The idea is that it's the client who is reponsible for running stuff, to make it possible to, eg, inject debugger support or other custom tools. So, rust-analzyer provides a more abstract representation of a cargo command, to make it easier for the client to make sense of it.

#4717 adds API for lazily computing code action edits.

#5188 adds status notification.

[matklad]

adds "memory usage" command: #5244

#4972 will switch to gzipping release artifacts.

rust-analyzer is available via rustup.

rust-analyzer f5a4a4b

The "officially recommended" binary at the moment is still the one from releases in this repo, but rustup one should be fine as well.
