Expand description

Implementations§

source§

impl<'tcx, 'a, Prov: Provenance, Extra, Bytes: AllocBytes> AllocRefMut<'a, 'tcx, Prov, Extra, Bytes>

Reading and writing.

source

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.

source

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.

source

pub fn write_uninit(&mut self) -> InterpResult<'tcx>

Mark the entire referenced range as uninitialized
