Overly long loop turn

[segeljakt]

Hi, I'm trying to use coc.nvim alongside rust-analyzer for my Rust editing and I'm getting these messages:

## Output channel: Rust Analyzer Language Server Trace

It seems something is not right. What do these messages mean?

That's just some internal profiling, which should be OK to ignore. Long term, we should debug each of those issues (we def should never block the main loop for 1 second), but this is mostly harmless today, and fixing this is not top priority.

Can we disable the "overly long loop turn" messages? Or downgrade them to a warning if they're okay to ignore?

They have already been downgraded to a warning: https://github.com/rust-analyzer/rust-analyzer/blob/b7afb6fc6ce6c94379c57d3bb64fea2a2064eeac/crates/rust-analyzer/src/main_loop.rs#L527

How I can disable this noisy notice? everytime key down, it shows

That only happens for from source builds I believe to nag rust-analyzer developers. I'm not sure how it is decided to not do this for release builds.

I'm use rustup's RA, to solve this #11558 (comment)
