Required Methods§

source

fn repr_discr<'tcx>( tcx: TyCtxt<'tcx>, ty: Ty<'tcx>, repr: &ReprOptions, min: i128, max: i128, ) -> (Integer, bool)

Finds the appropriate Integer type and signedness for the given signed discriminant range and #[repr] attribute. N.B.: u128 values above i128::MAX will be treated as signed, but that shouldn’t affect anything, other than maybe debuginfo.

Object Safety§

This trait is not object safe.
