pub enum SubFn {
Poly(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.
