This turns on the Clippy warning `redundant_clone`, which detects unnecessary calls to `.clone()` (and `.to_string()`). It is an unstable warning and so might reports some false positives. If we find any, we can suppress the warning there.

What
I noticed a few extra calls to
.clone()while working on an unrelated refactor. I want to remove them for brevity and simplicity; I don't expect a performance improvement.This turns on the Clippy warning

How
I turned the warning on and applied fixes everywhere.
I also saw a few that the lint didn't catch, which I fixed myself.
