Struct rustc_middle::ty::util::Discr

pub struct Discr<'tcx> {
    pub val: u128,
    pub ty: Ty<'tcx>,
}

Fields

val: u128

Bit representation of the discriminant (e.g., -128i8 is 0xFF_u128).

ty: Ty<'tcx>

Implementations

pub fn wrap_incr(self, tcx: TyCtxt<'tcx>) -> Self

Adds 1 to the value and wraps around if the maximum for the type is reached.

pub fn checked_add(self, tcx: TyCtxt<'tcx>, n: u128) -> (Self, bool)
