This module provides a few things: #. A handy function for getting an object down to something that can be JSON serialized. See :func:`.to_primitive`. #. Wrappers around :func:`.loads` and :func:`.dumps`. The :func:`.dumps` wrapper will automatically use :func:`.to_primitive` for you if needed. #. This sets up ``anyjson`` to use the :func:`.loads` and :func:`.dumps` wrappers if ``anyjson`` is available.

Handy for JSON serialization. We can optionally handle instances, but since this is a recursive function, we could have cyclical data structures. To handle cyclical data structures we could track the actual objects visited in a set, but not all objects are hashable. Instead we just track the depth of the object inspections and don't go too deep. Therefore, ``convert_instances=True`` is lossy ... be aware. If the object cannot be converted to primitive, it is returned unchanged if fallback is not set, return fallback(value) otherwise. .. versionchanged:: 2.22 Added *fallback* parameter. .. versionchanged:: 1.3 Support UUID encoding. .. versionchanged:: 1.6 Dictionary keys are now also encoded.
