A thing that we can project into, and that has a layout.

Required Methods

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

Get the layout.

fn meta<'mir, M>( &self, ecx: &InterpCx<'mir, 'tcx, M> ) -> Result<MemPlaceMeta<<M as Machine<'mir, 'tcx>>::Provenance>, InterpErrorInfo<'tcx>>where M: Machine<'mir, 'tcx, Provenance = Prov>,

Get the metadata of a wide value.

fn offset_with_meta( &self, offset: Size, meta: MemPlaceMeta<Prov>, layout: TyAndLayout<'tcx, Ty<'tcx>>, cx: &impl HasDataLayout ) -> Result<Self, InterpErrorInfo<'tcx>>

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.

Provided Methods

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

fn offset( &self, offset: Size, layout: TyAndLayout<'tcx, Ty<'tcx>>, cx: &impl HasDataLayout ) -> Result<Self, InterpErrorInfo<'tcx>>

fn transmute( &self, layout: TyAndLayout<'tcx, Ty<'tcx>>, cx: &impl HasDataLayout ) -> Result<Self, InterpErrorInfo<'tcx>>
