Clippy is really helpful. I use it regularly, but fix the findings manually. (To imprint it into my workflow.)
There is even the possibility to use it inside your IDE in addition to the LSP server.
"Note: Clippy is meant to be used with a generous sprinkling of #[allow(..)]s through your code. So if you disagree with a lint, don't feel bad disabling them for parts of your code or the whole project."
