public void take_view_user_data (size_t view_id, owned Object? user_data)
Sets the user data for the view_id.
The function assumes ownership of the user_data. The user_data can be null,
which unsets the current user data for the view.
This is primarily aimed as a helper for backend implementations of the manual query views ( e_book_client_view_flags_manual_query).
