Use structured suggestion for restricting bounds When a trait bound is not met and restricting a type parameter would make the restriction hold, use a structured suggestion pointing at an appropriate place (type param in param list or `where` clause). Account for opaque parameters where instead of suggesting extending the `where` clause, we suggest appending the new restriction: `fn foo(impl Trait + UnmetTrait)`. 2019-10-07 14:23:56 -07:00			`\| \|`
