pub struct PlaceTy<'tcx, Prov: Provenance = AllocId> {
    place: Place<Prov>,
    pub layout: TyAndLayout<'tcx>,
}

Fields

place: Place<Prov>

layout: TyAndLayout<'tcx>

Implementations

impl<'tcx, Prov: Provenance> PlaceTy<'tcx, Prov>

pub(super) fn place(&self) -> &Place<Prov>

pub fn as_mplace_or_local( &self ) -> Either<MPlaceTy<'tcx, Prov>, (usize, Local, Option<Size>)>

A place is either an mplace or some local.

pub fn assert_mem_place(&self) -> MPlaceTy<'tcx, Prov>

Trait Implementations

impl<'tcx, Prov: Clone + Provenance> Clone for PlaceTy<'tcx, Prov>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Prov: Provenance> Debug for PlaceTy<'_, Prov>

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

Formats the value using the given formatter.

impl<'tcx, Prov: Provenance> From<MPlaceTy<'tcx, Prov>> for PlaceTy<'tcx, Prov>

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

Converts to this type from the input type.

impl<'tcx, Prov: Provenance> Projectable<'tcx, Prov> for PlaceTy<'tcx, Prov>

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

Get the layout.

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

Get the metadata of a wide value.

fn offset_with_meta<'mir, M: Machine<'mir, 'tcx, Provenance = Prov>>( &self, offset: Size, mode: OffsetMode, meta: MemPlaceMeta<Prov>, layout: TyAndLayout<'tcx>, ecx: &InterpCx<'mir, 'tcx, M> ) -> InterpResult<'tcx, Self>

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

fn to_op<'mir, M: Machine<'mir, 'tcx, Provenance = Prov>>( &self, ecx: &InterpCx<'mir, 'tcx, M> ) -> InterpResult<'tcx, OpTy<'tcx, M::Provenance>>

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

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

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

fn offset<'mir, M: Machine<'mir, 'tcx, Provenance = Prov>>( &self, offset: Size, layout: TyAndLayout<'tcx>, ecx: &InterpCx<'mir, 'tcx, M> ) -> InterpResult<'tcx, Self>

fn transmute<'mir, M: Machine<'mir, 'tcx, Provenance = Prov>>( &self, layout: TyAndLayout<'tcx>, ecx: &InterpCx<'mir, 'tcx, M> ) -> InterpResult<'tcx, Self>

impl<'tcx, Prov: Provenance> Writeable<'tcx, Prov> for PlaceTy<'tcx, Prov>

fn as_mplace_or_local( &self ) -> Either<MPlaceTy<'tcx, Prov>, (usize, Local, Option<Size>, TyAndLayout<'tcx>)>

fn force_mplace<'mir, M: Machine<'mir, 'tcx, Provenance = Prov>>( &self, ecx: &mut InterpCx<'mir, 'tcx, M> ) -> InterpResult<'tcx, MPlaceTy<'tcx, Prov>>

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.
