impl<SL: Slot> MemorySlice for UnimplementedMemorySlice<SL>

§

type SlotType = SL

The associate type to define how to access slots from a memory slice.
§

type SlotIterator = UnimplementedMemorySliceSlotIterator<SL>

The associate type to define how to iterate slots in a memory slice.
source§

fn iter_slots(&self) -> Self::SlotIterator

Iterate object slots within the slice. If there are non-reference values in the slice, the iterator should skip them.
source§

fn object(&self) -> Option<ObjectReference>

The object which this slice belongs to. If we know the object for the slice, we will check the object state (e.g. mature or not), rather than the slice address. Normally checking the object and checking the slice does not make a difference, as the slice is part of the object (in terms of memory range). However, if a slice is in a different location from the object, the object state and the slice can be hugely different, and providing a proper implementation of this method for the owner object is important.
source§

fn start(&self) -> Address

Start address of the memory slice
source§

fn bytes(&self) -> usize

Size of the memory slice
source§

fn copy(_src: &Self, _tgt: &Self)

impl<SL: PartialEq + Slot> PartialEq for UnimplementedMemorySlice<SL>

source§

fn eq(&self, other: &UnimplementedMemorySlice<SL>) -> bool

This method tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
