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)

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
