Could you paste the output of "Rust Language Server" please?

Here is the output of the RLS log:

I believe it's related to rust-lang/rls#263.

[damienstanton]

Thanks, I will track that issue as well.

[damienstanton]

@KalitaAlexey In case it helps, I've been trying to keep track of the multiple RLS tickets going on. It seems all of these are -although not quite dupes- caused by the same set of bugs. #296, #305, #307, #310

[damienstanton]

None of these issues are apparent now (a year later), and the plugin seems to handle RLS using default and nightly quite well. Closing!
