dvdotsenko / dataclass_recursive_deserialize.py
Created November 25, 2020 04:02
Python Recursive / Nested `dataclass` instances deserialization worker. Simple.
"""
Code that creates nested `dataclass` instances tree from JSON data.
Somewhat similar to what Pydantic, Schematics do out of the box,
but native Python dataclasses don't do automatically.
See discussion here for context
https://stackoverflow.com/questions/51564841/creating-nested-dataclass-objects-in-python
See tests on the bottom of this file usage examples.
Tested on Python 3.9
