sourcepub fn to_scalar_int(&self) -> InterpResult<'tcx, ScalarInt>
pub fn to_scalar_int(&self) -> InterpResult<'tcx, ScalarInt>
Return the immediate as a ScalarInt
. Ensures that it has the size that the layout of the
immediate indicates.
pub fn to_const_int(self) -> ConstInt
pub fn to_pair( self, cx: &(impl HasTyCtxt<'tcx> + HasParamEnv<'tcx>), ) -> (Self, Self)
sourcefn offset_(
&self,
offset: Size,
layout: TyAndLayout<'tcx>,
cx: &impl HasDataLayout,
) -> Self
fn offset_( &self, offset: Size, layout: TyAndLayout<'tcx>, cx: &impl HasDataLayout, ) -> Self
Compute the “sub-immediate” that is located within the base
at the given offset with the
given layout.

Layout§
Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
