Arguments: receiver (Callable): A function or an instance method which is to receive signals. Receivers must be hashable objects. if weak is :const:`True`, then receiver must be weak-referenceable. Receivers must be able to accept keyword arguments. If receivers have a `dispatch_uid` attribute, the receiver will not be added if another receiver already exists with that `dispatch_uid`. sender (Any): The sender to which the receiver should respond. Must either be a Python object, or :const:`None` to receive events from any sender. weak (bool): Whether to use weak references to the receiver. By default, the module will attempt to use weak references to the receiver objects. If this parameter is false, then strong references will be used. dispatch_uid (Hashable): An identifier used to uniquely identify a particular instance of a receiver. This will usually be a string, though it may be anything hashable. retry (bool): If the signal receiver raises an exception (e.g. ConnectionError), the receiver will be retried until it runs successfully. A strong ref to the receiver will be stored and the `weak` option will be ignored.
