Avyra

v1.1.0 : Lightweight, thread-safe publish-subscribe event bus.

pip install avyra

from enum import Enum, auto
from avyra import EventBus

class Message(Enum):
    SENT = auto()
    READ = auto()

bus = EventBus()
bus.register(Message)

@bus.on(Message.SENT)
def handler(event, payload):
    print(f"Sent: {payload}")

bus.emit(Message.SENT, "Hello!")

• Typed events : Enum members, not strings.
• Thread-safe : RLock-protected mutations, snapshot dispatch.
• Zero dependencies : pure Python.
