Enum SubFn

Help

pub enum SubFn {
    Poly(DefId, EarlyBinder<PolyFnSig>, GenericArgs),
    Mono(PolyFnSig),
}

Expand description

SubFn lets us reuse most of the same code for check_fn_subtyping for both the case where we have an early-bound function signature (e.g., for a trait method???) and versions without, e.g. a plain closure against its FnTraitPredicate obligation.
