A-impl-trait Area: impl Trait. Universally / existentially quantified anonymous types with static dispatch. C-bug Category: This is a bug. I-crash Issue: The compiler crashes (SIGSEGV, SIGABRT, etc). Use I-ICE instead when the compiler panics. T-compiler Relevant to the compiler team, which will review and decide on the PR/issue.

Code

struct Foo<F: FnOnce(T), F: FnOnce(T)> {
    f: FooImpl,
}

type FooImpl = Foo<FooImpl, impl FnOnce(ImplT)>;

fn bar() -> FooImpl {}

does not seem to be fixed by the new solver
