rust-analyzer
is a pretty good LSP, and works in most modern text editors.
My advice? Just pick an editor and stick to it.
VSCode? Sure.
Jetbrains? Good choice.
Hell, Emacs? Why not?
I personally use Neovim, and it just works. No matter what I’m programming in, I’m still at home.
Just pick an editor that works for you. I’d suggest VSCode. Use VSCodium for a true FOSS experience, or Helix for a beginner friendly terminal editor.
If you really just want something Rust-focused, there’s RustRover from Jetbrains, but that’s about it.
