Add trait diff highlighting logic and use it in E0277 When a trait is not implemented for a type, but there is an `impl` for another type or different trait params, we format the output to use highlighting in the same way that E0308 does for types. The logic accounts for 3 cases: - When both the type and trait in the expected predicate and the candidate are different - When only the types are different - When only the trait generic params are different For each case, we use slightly different formatting and wording. 2024-10-24 22:16:43 +00:00			= help: the trait `SliceIndex<[{integer}]>` is not implemented for `i32`
