# heapOffset

The distance, in bytes, from the beginning of the heap to the first byte of the resource, if you allocated the resource on a heap.

## Declaration

```swift
var heapOffset: Int { get }
```

## Discussion

Discussion If the heap is not a placement heap (MTLHeapType.placement), the value is always 0 and should be ignored.
