lidavidm commented on ARROW-5722:
---------------------------------
[~csun], I have some basic implementations. Printing nested arrays is
difficult; I've punted on that for StructArray/ListArray. Really, we need Array
to have a Debug trait bound as well - is that acceptable?
In the future, we may also want a pretty-printer API to make nested arrays look
better (with indentation, etc).
