Extensions to attrs

The following libraries build on attrs to provide additional functionality:

• cattrs — for structuring and unstructuring data

• related — for creating nested object models that can be serialized to and de-serialized from nested python dictionaries

• valid8 — provides an alternate way to add validation to attributes, supporting various coding styles to define your validation functions and validation exception types/messages.

• serde — a performant serialization / deserialization extension to and from plain dicts.
