// Test for issue #57362, ensuring that the self ty is shown in cases of higher-ranked lifetimes // conflicts: the `expected` and `found` trait refs would otherwise be printed the same, leading // to confusing notes such as: // = note: expected type `Trait` // found type `Trait` // from issue #57362 trait Trait { fn f(self); } impl Trait for fn(&T) { fn f(self) { println!("f"); } } fn f() { let a: fn(_) = |_: &u8| {}; a.f(); //~ ERROR not general enough } // extracted from a similar issue: #57642 trait X { type G; fn make_g() -> Self::G; } impl<'a> X for fn(&'a ()) { type G = &'a (); fn make_g() -> Self::G { &() } } fn g() { let x = ::make_g(); //~ ERROR not general enough } fn main() {}
