A read-only view of a collection of metadata objects.
Defined in header <boost/mysql/metadata_collection_view.hpp>
using metadata_collection_view = boost::span< const metadata >;
The object doesn't own the storage for the metadata objects. These are typically
owned by a results or execution_state object. This view
is valid as long as the memory allocated for the metadata objects remain valid.
