NativeArrayOptions lets you control if memory should be cleared on allocation or left uninitialized.
NativeArrayOptions.ClearMemory is the default.
| UninitializedMemory | Uninitialized memory can improve performance, but results in the contents of the array elements being undefined. In performance sensitive code it can make sense to use NativeArrayOptions.Uninitialized, if you are writing to the entire array right after creating it without reading any of the elements first. |
| ClearMemory | Clear NativeArray memory on allocation. |
