Delegation: fix ICE on wrong `Self` instantiation fixes https://github.com/rust-lang/rust/issues/119921 fixes https://github.com/rust-lang/rust/issues/119919 There is no way to instantiate `Self` param for caller in delegation item if 1. callee is a trait method && callee contains `Self` param 2. delegation item isn't an associative item In general, we can consider `Self` param as independent type param in these cases: ```rust trait Trait { fn foo(_: Option<&Self>) {...} } reuse Trait::foo; // will be desugared to: fn foo<T: Trait>(x: Option<&T>) { Trait::foo(x) } ``` But this requires early bound parameters support. For now, I suggest banning such cases to avoid ICE's. r? ``@petrochenkov`` |
