Expand description

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

Required Methods§

source

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

Get the layout.

source

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

Get the metadata of a wide value.

source

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

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

source

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§

source

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.

source

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>,

source

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>,

Object Safety§

This trait is not object safe.
