Detailed Description

This file defines the context_t structure and function objects for metadata database operations.

The context_t structure encapsulates a database connection and schema information, providing a convenient way to manage database operations. The get_context_fn, pull_fn, push_fn, and remove_fn function objects provide callable interfaces for obtaining a context_t, pulling data from the database, pushing data to the database, and removing data from the database, respectively.

Note

The function objects are designed to be used in functional programming contexts, allowing for concise and expressive code when performing database operations. The use of coroutines in the pull_fn and push_fn function objects enables efficient and asynchronous processing of data, allowing for non-blocking operations and improved performance when interacting with the database.

The context_t structure and function objects are part of the oxy::directory namespace, providing a modular and organized approach to managing database operations within the oxy-sync-directory library.
