Columns of tables_to_concat are concatenated vertically to return a single table.

Concatenates views[i]'s bitmask from the bits [views[i].offset(), views[i].offset() + views[i]....
rmm::cuda_stream_view const get_default_stream()
Get the current default stream.
rmm::device_async_resource_ref get_current_device_resource_ref()
Get the current device memory resource reference.
