A generic interface wrapping multiple backends to provide a consistent pubsub API.

Usage

To use it, you need to implement your pubsub implementation from interfaces or use backends from aio_pubsub.backends package:

from aio_pubsub.backends.memory import MemoryPubSub
pubsub = MemoryPubSub()
# Create subscriber
subscriber = await pubsub.subscribe("a_chan")

# Push message
await pubsub.publish("a_chan", "hello world!")
await pubsub.publish("a_chan", "hello universe!")

# And listening channel
try:
    async for message in subscriber:
        print(message, flush=True)
except KeyboardInterrupt:
    print("Finish listening")

Supported backends

Disclaimer: I would not advise you to use this backend, because it is shown only for testing purposes. Better develop your own implementation.
