Function rustc_trait_selection::traits::object_safety::receiver_for_self_ty

fn receiver_for_self_ty<'tcx>(
    tcx: TyCtxt<'tcx>, 
    receiver_ty: Ty<'tcx>, 
    self_ty: Ty<'tcx>, 
    method_def_id: DefId
) -> Ty<'tcx>

Performs a type substitution to produce the version of receiver_ty when Self = self_ty. For example, for receiver_ty = Rc<Self> and self_ty = Foo, returns Rc<Foo>.
