There was a problem hiding this comment.
enumerate() itself doesn’t guard against overflow, so guarding only at idx + 1 doesn’t add real safety.
In any case, I think idx.checked_add(1).unwrap() would make more sense.

Hang on, there is no potential overflow, key_index has the range 1..settings.selectors.len()
They all optimise to the same anyway: https://godbolt.org/z/f4WzhP1vf
