Required Methods

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

Gets this value’s layout.

fn to_op(
    &self,
    ecx: &InterpCx<'mir, 'tcx, M>
) -> Result<OpTy<'tcx, <M as Machine<'mir, 'tcx>>::PointerTag>, InterpErrorInfo<'tcx>>

Makes this into an OpTy.

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

Creates this from an MPlaceTy.

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

Projects to the given enum variant.

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

Projects to the n-th field.
