Welcome to asyncio_dispatch’s documentation!

aysincio_dispatch is a signal dispatcher for the asyncio event loop.

Synopsis

Many callbacks can be connected to a Signal. When the Signal is triggered using its send() method, all connected callbacks will be scheduled for asynchronous execution.

Connections can optionally be made using with types of filters, senders and keys. If filters are used, the callback is only scheduled for execution if the Signal is sent with at least one matching sender or key. A sender can be any object, while a key is more likely to be a string. Under the hood, they use id() and hash() respectively.

Callbacks are invoked with keyword arguments that allow the callback to determine which Signal is calling it and which senders and keys were specified. Additional keyword arguments can be added to the Signal when it is instantiated, and their default values can be replaced when the Signal is sent.
