}Expand description
A reference to some allocation that was already bounds-checked for the given region and had the on-access machine hooks run.

Reading and writing.
sourcepub fn write_scalar(
&mut self,
range: AllocRange,
val: Scalar<Prov>
) -> InterpResult<'tcx>
pub fn write_scalar(
&mut self,
range: AllocRange,
val: Scalar<Prov>
) -> InterpResult<'tcx>
range is relative to this allocation reference, not the base of the allocation.
sourcepub fn write_ptr_sized(
&mut self,
offset: Size,
val: Scalar<Prov>
) -> InterpResult<'tcx>
pub fn write_ptr_sized(
&mut self,
offset: Size,
val: Scalar<Prov>
) -> InterpResult<'tcx>
offset is relative to this allocation reference, not the base of the allocation.
sourcepub fn write_uninit(&mut self) -> InterpResult<'tcx>
pub fn write_uninit(&mut self) -> InterpResult<'tcx>
Mark the entire referenced range as uninitialized
