prefect.serializers
Serializer
class and include a type
string that
allows them to be referenced without referencing the actual class. For example, you
can get often specify the JSONSerializer
with the string “json”. Some serializers
support additional settings for configuration of serialization. These are stored on
the instance so the same settings can be used to load saved objects.
All serializers must implement dumps
and loads
which convert objects to bytes and
bytes to an object respectively.
prefect_json_object_encoder
JSONEncoder.default
for encoding objects into JSON with extended type support.
Raises a TypeError
to fallback on other encoders on failure.
prefect_json_object_decoder
JSONDecoder.object_hook
for decoding objects from JSON when previously encoded
with prefect_json_object_encoder
