E0599 suggestions and elision of generic argument if no canditate is found fixes #81576 changes: In error E0599 (method not found) generic argument are eluded if the method was not found anywhere. If the method was found in another inherent implementation suggest that it was found elsewhere. Example ```rust struct Wrapper<T>(T); struct Wrapper2<T> { x: T, } impl Wrapper2<i8> { fn method(&self) {} } fn main() { let wrapper = Wrapper(i32); wrapper.method(); let wrapper2 = Wrapper2{x: i32}; wrapper2.method(); } ``` ``` Error[E0599]: no method named `method` found for struct `Wrapper<_>` in the current scope .... error[E0599]: no method named `method` found for struct `Wrapper2<i32>` in the current scope ... = note: The method was found for Wrapper2<i8>. ``` I am not very happy with the ```no method named `test` found for struct `Vec<_, _>` in the current scope```. I think it might be better to show only one generic argument `Vec<_>` if there is a default one. But I haven't yet found a way to do that,
