decorator syntax for marshmallow meta attributes (with inheritance)

Decorators communicate that the behavior of a class is being modified and are more concise when only a few meta attributes are needed. Making inheritance the default further reduces the boilerplate needed to make minor changes to a subclass.

Install

pip install marshmallow-meta

from marshmallow_meta import meta
