Function rustc_ty_utils::structural_match::has_structural_eq_impl
source ยท fn has_structural_eq_impl<'tcx>(tcx: TyCtxt<'tcx>, adt_ty: Ty<'tcx>) -> bool
Expand description
This method returns true if and only if adt_ty
itself has been marked as
eligible for structural-match: namely, if it implements
StructuralPartialEq
(which is injected by #[derive(PartialEq)]
).
Note that this does not recursively check if the substructure of adt_ty
implements the trait.
