datadispatch
datadispatch provides a dispatch mechanism (a.k.a. polymorphism) like functools.singledispatch, but it operates on data instead of types. This is useful if you are creating simple data-centric applications where you want polymorphism à la carte without resorting to types or classes.
datadispatch is available through pip: pip install datadispatch
Usage example
from datadispatch import datadispatch
@datadispatch(lambda args, _: args[0].get('type'))
def handle(message):
raise ValueError('cannot handle message: {}'.format(message))
@handle.register('ping')
def _(message):
return 'you sent ping'
@handle.register('pong')
def _(message):
return 'you sent pong'
print(handle(
{'type': 'ping', 'payload': 'hello'}
))
