Address #85991 Suggest the `impl Trait` return type syntax if the user tried to return a generic parameter and we get a type mismatch The suggestion is not emitted if the param appears in the function parameters, and only get the bounds that actually involve `T: ` directly It also checks whether the generic param is contained in any where bound (where it isn't the self type), and if one is found (like `Option<T>: Send`), it is not suggested. This also adds `TyS::contains`, which recursively vistits the type and looks if the other type is contained anywhere |
