nr.interface

Interface definitions for Python. Inspired by zope.interface.

from nr.interface import Interface, implements, override

class Pet(Interface):

  def make_sound(self) -> str:
    pass

@implements(Pet)
class Dog:

  @override
  def make_sound(self) -> str:
    return 'Bark!'

assert 'make_sound' in Pet.members
assert Pet.implemented_by(Dog)
assert list(Pet.implementations()) == [Dog]
