Or, if you prefer editing your settings.json by hand:
This should give you Clippy errors/warnings inline like you'd expect (please don't judge my code ) :
Have you found this to be slower? I ended up switching it off. I had issues where it took a lot longer to update the highlighting in vscode and got the alert “waiting for save actions from rust-analyzer”
I occasionally have that issue too (with checkOnSave.command set to check). I wait for a few seconds and everything goes back to normal.
I have that too with it set to “check” but set to “clippy” I ended up having to cancel the save action after a couple minutes of waiting.
