Detailed Description

A non-owning, immutable view of device data as a column of elements, some of which may be null as indicated by a bitmask.

A scalar_column_view can be constructed explicitly from a cudf::column_view.

Unless otherwise noted, the memory layout of the scalar_column_view's data and bitmask is expected to adhere to the Arrow Physical Memory Layout Specification: https://arrow.apache.org/docs/memory_layout.html

Because scalar_column_view is non-owning, no device memory is allocated nor freed when scalar_column_view objects are created or destroyed.
