Fix #101351. When an associated type on a type parameter is used, and the type parameter isn't constrained by the correct trait, suggest the appropriate trait bound: ``` error[E0220]: associated type `Associated` not found for `T` --> file.rs:6:15 | 6 | field: T::Associated, | ^^^^^^^^^^ there is a similarly named associated type `Associated` in the trait `Foo` | help: consider restricting type parameter `T` | 5 | struct Generic<T: Foo> { | +++++ ``` When an associated type on a type parameter has a typo, suggest fixing it: ``` error[E0220]: associated type `Baa` not found for `T` --> $DIR/issue-55673.rs:9:8 | LL | T::Baa: std::fmt::Debug, | ^^^ there is a similarly named associated type `Bar` in the trait `Foo` | help: change the associated type name to use `Bar` from `Foo` | LL | T::Bar: std::fmt::Debug, | ~~~ ```
