pub(in ty::layout) fn scalar_pair(
    &self,
    a: Scalar,
    b: Scalar
) -> Layout

pub(in ty::layout) fn univariant_uninterned(
    &self,
    ty: Ty<'tcx>,

impl<'tcx> LayoutCx<'tcx, TyCtxt<'tcx>>

pub(in ty::layout) fn generator_saved_local_eligibility(
    &self,
    info: &GeneratorLayout<'tcx>
) -> (BitSet<GeneratorSavedLocal>, IndexVec<GeneratorSavedLocal, SavedLocalEligibility>)

Compute the eligibility and assignment of each local.

pub(in ty::layout) fn generator_layout(
    &self,
    ty: Ty<'tcx>,
    def_id: DefId,
    substs: SubstsRef<'tcx>
) -> Result<&'tcx Layout, LayoutError<'tcx>>

Compute the full generator layout.

pub(in ty::layout) fn record_layout_for_printing(
    &self,
    layout: TyAndLayout<'tcx>
)

This is invoked by the layout_raw query to record the final layout of each type.

    &self,
    layout: TyAndLayout<'tcx>
)
