Trait Implementations

impl<'tcx, Prov> Clone for OpTy<'tcx, Prov>

where Prov: Clone + Provenance,

fn clone(&self) -> OpTy<'tcx, Prov>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<Prov> Debug for OpTy<'_, Prov>

where Prov: Provenance,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'tcx, Prov> From<ImmTy<'tcx, Prov>> for OpTy<'tcx, Prov>

where Prov: Provenance,

fn from(val: ImmTy<'tcx, Prov>) -> OpTy<'tcx, Prov>

Converts to this type from the input type.

impl<'tcx, Prov> From<MPlaceTy<'tcx, Prov>> for OpTy<'tcx, Prov>

where Prov: Provenance,

fn from(mplace: MPlaceTy<'tcx, Prov>) -> OpTy<'tcx, Prov>

Converts to this type from the input type.

impl<'tcx, Prov> Projectable<'tcx, Prov> for OpTy<'tcx, Prov>

where Prov: Provenance,

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

Get the layout.

fn meta(&self) -> MemPlaceMeta<Prov>

Get the metadata of a wide value.

fn offset_with_meta<'mir, M>( &self, offset: Size, mode: OffsetMode, meta: MemPlaceMeta<Prov>, layout: TyAndLayout<'tcx, Ty<'tcx>>, ecx: &InterpCx<'mir, 'tcx, M> ) -> Result<OpTy<'tcx, Prov>, InterpErrorInfo<'tcx>>

where M: Machine<'mir, 'tcx, Provenance = Prov>,

Offset the value by the given amount, replacing the layout and metadata.

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

where M: Machine<'mir, 'tcx, Provenance = Prov>,

Convert this to an OpTy. This might be an irreversible transformation, but is useful for reading from this thing.

fn len<'mir, M>( &self, ecx: &InterpCx<'mir, 'tcx, M> ) -> Result<u64, InterpErrorInfo<'tcx>>

where M: Machine<'mir, 'tcx, Provenance = Prov>,

Get the length of a slice/string/array stored here.

fn offset<'mir, M>( &self, offset: Size, layout: TyAndLayout<'tcx, Ty<'tcx>>, ecx: &InterpCx<'mir, 'tcx, M> ) -> Result<Self, InterpErrorInfo<'tcx>>

where M: Machine<'mir, 'tcx, Provenance = Prov>,

fn transmute<'mir, M>( &self, layout: TyAndLayout<'tcx, Ty<'tcx>>, ecx: &InterpCx<'mir, 'tcx, M> ) -> Result<Self, InterpErrorInfo<'tcx>>

where M: Machine<'mir, 'tcx, Provenance = Prov>,

impl<'tcx, Prov> Readable<'tcx, Prov> for OpTy<'tcx, Prov>

where Prov: Provenance,

fn as_mplace_or_imm(&self) -> Either<MPlaceTy<'tcx, Prov>, ImmTy<'tcx, Prov>>

impl VisitProvenance for OpTy<'_, Provenance>

fn visit_provenance(&self, visit: &mut VisitWith<'_>)

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.
