Required methods

fn layout(&self) -> TyAndLayout<'tcx>

Gets this value’s layout.

fn to_op(
    &self,
    ecx: &InterpCx<'mir, 'tcx, M>
) -> InterpResult<'tcx, OpTy<'tcx, M::PointerTag>>

Makes this into an OpTy.

fn from_mem_place(mplace: MPlaceTy<'tcx, M::PointerTag>) -> Self

Creates this from an MPlaceTy.

fn project_downcast(
    &self,
    ecx: &InterpCx<'mir, 'tcx, M>,
    variant: VariantIdx
) -> InterpResult<'tcx, Self>

Projects to the given enum variant.

fn project_field(
    &self,
    ecx: &InterpCx<'mir, 'tcx, M>,
    field: usize
) -> InterpResult<'tcx, Self>

Projects to the n-th field.
