Description:

If I'm not mistaken, the RLS linting is called whenever a key is pressed in the editor. This brings two issues:

1: RLS returns when I'm still typing and it gives wrong results.
2: When I start typing, there is always 1 core that is used at 100%, and my cpu don't like it (very noticeable on my weak laptop / barely noticeable on my tower).

Allowing a delay in ms in the configuration would fix these issues. For example, if I set the delay to 1000 ms, source linting will only be called after I stopped typing for 1 sec.

Example:

"rust.rls": {
    "linting_delay": 1000,
}
