Lists of Native Arrays and Disposing

[tim_jones]

What is it specifically that you’re missing in NativeList? There are some helpful extension methods here:

NativeList Remove and RemoveAt methods

If you don’t care about order, there is a fast remove using RemoveAtSwapBack /// <summary> /// Truncates the list by replacing the item at the specified index with the last item in the list. The list /// is shortened by one. /// </summary> /// <param name="index">The index of the item to delete.</param> /// <exception cref="ArgumentOutOfRangeException">If index is negative or >= <see cref="Length"/>.</exception> public void RemoveAtSwapBac…

NativeList itself has an InsertRangeWithBeginEnd() method, which I guess could be used to implement a normal Insert() method?

Since you’re in the Burst forum, I’ll mention that built-in collections like NativeArray and NativeList have some built-in niceties in Burst, like alias checking to make it more likely that loops will be vectorized. You can technically build this yourself for your own collection types - see here for details - but it’s non-trivial to get it right.
