Appendix 04 -- Rust Language Server vs Rust Analyzer

[abraithwaite]

Hey friends! Was reading the appendix and saw that the rust language server was mentioned as a useful development tool to setup for use by text editors/IDEs:

https://doc.rust-lang.org/stable/book/appendix-04-useful-development-tools.html#ide-integration-using-the-rust-language-server

However, one of the author's of that project claim that RLS is now the past and rust-analyzer is the future:

rust-lang/rls#742 (comment)

It's not mentioned in the readme of RLS yet, but it was a bit confusing trying to figure out what to setup my first time. Not sure there's much to do now, but it might be useful for others to know in a subsequent version of this book that RLS is (will be?) no longer.

Hi there,

As always, cutting edge comments are newer than the book. rust-lang/rust-analyzer#4224 is the tracking issue for this transition, once it's ready, the book will be updated to talk about it. While it's great for many people, the book doesn't target the cutting edge.

I'm gonna leave this issue open as a "we should update this when it's ready." :) Thank you!

Totally understood! Thanks!
