Suggest trait bounds for used associated type on type param 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, \| ~~~ ``` 2023-09-29 03:16:11 +00:00			`// run-rustfix`
