Suggest borrowing arguments in generic positions when trait bounds are satisfied

2024-11-14T04:29:40+00:00

This subsumes the suggestions to borrow arguments with `AsRef`/`Borrow` bounds and those to borrow arguments with `Fn` and `FnMut` bounds. It works for other traits implemented on references as well, such as `std::io::Read`, `std::io::Write`, and `core::fmt::Write`. Incidentally, by making the logic for suggesting borrowing closures general, this removes some spurious suggestions to mutably borrow `FnMut` closures in assignments, as well as an unhelpful suggestion to add a `Clone` constraint to an `impl Fn` argument.

Provide borrow-instead-of-move suggestions for calls of fn-like items from other crates

This also downgrades its applicability to MaybeIncorrect. Its suggestion can result in ill-typed code when the type parameter it suggests providing a different generic argument for appears elsewhere in the callee's signature or predicates.
