De/serialize YAML payloads using Python type hints.

Project description


Databind is a library inspired by Jackson-databind to describe and bind data models for object-oriented programming. The databind.yaml module provides functionality to (de-) serialize YAML payloads from/to Python objects.

Note: This module is just a thin wrapper that provides utility functions, combining the functionality of databind.json with PyYAML.


from typing import Optional
from databind.core import datamodel
from databind.yaml import from_str

class Geolocation:
  latitude: float
  longitude: float
  altitude: Optional[float] = None

class ResolvedLocation:
  query: str
  location: Geolocation

london = from_str(ResolvedLocation, '''
query: London
  latitude: 51.507351
  longitude: -0.127758

assert london == ResolvedLocation("London", Geolocation(51.507351, -0.127758))
