Reference type support

See original GitHub issue

Hi,

Good job with this! It solves a real need for users out there.

Have you considered/planned to support reference types in NativeMemoryArray?

Seeing this line makes me think so. https://github.com/Cysharp/NativeMemoryArray/blob/8a9eac144e518bf1073725e4a923c3e1989ae568/tests/NativeMemoryArray.Tests/NativeArrayTest.cs#L137

POH, still data exsits in managed heap. If the NativeMemoryArray supports reference types, record the reference address in the NativeMemory area. We have to ensure that this reference address does not change and that it is not erased by GC since it is tracked.

Thanks for info.

In this case, I don’t think it would be useful.

If we want to support a large reference array, my first idea was to create a ChunkedArray. This would support sequential writes and ReadOnlySequence<T> reads.

I decided not to brush up on this idea, as it doesn’t seem to be very useful.
