Implementations on Foreign Types

impl IntegerExt for Integer[src]

pub fn from_attr<C: HasDataLayout>(cx: &C, ity: IntType) -> Integer[src]

Gets the Integer type from an attr::IntType.

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

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.
