| dataPointer | Pointer to the preallocated data. |
| length | Number of elements. The length of the data in bytes will be computed automatically from this. |
| allocator | Allocation strategy to use. |
NativeArray<T> A new NativeArray, allocated with the given strategy and wrapping the provided data.
Converts an existing buffer to a NativeArray.
This method can be used to turn an existing buffer into a NativeArray, to be fed to the Unity API for processing. Ownership of the data is controlled via the allocation strategy provided via the allocator argument. Allocator.None can be used in case the data is owned externally, while the others can be used to transfer control to the NativeArray.
