What's the output of :CocCommand rust-analyzer.serverVersion rust-analyzer 0.0.0 (75b22326d 2022-07-03)

macOS 12.4

[fannheyward]

Can't reproduce.

1. cd /tmp
2. cargo new a1 && cd a1
3. nvim src/main.rs

Set "rust-analyzer.trace.server": "verbose" in your coc-settings.json, reproduce your issue and check :CocCommand workspace.showOutput rust-analyzer

--workspace was unexpected.

[TENX-S]

Whoops. https://github.com/rust-lang/rust-analyzer/issues/6589#issuecomment-1094132030 comment this line works for me, anything wrong about it?

"rust-analyzer.checkOnSave.command": "fmt",

[fannheyward]

I don't think you can use fmt as checkOnSave command.

[TENX-S]

Alright.
