Detailed Description

This namespace contains function objects and operations related to container metadata management in the metadata database.

The oxy::api::metadata namespace provides function objects for retrieving, pulling, and pushing container metadata records in the metadata database. It is designed to be used in a constexpr context for compile-time evaluation of metadata management operations.
