GitHub user hanishi created a discussion: pekko-py: Pekko Typed style actors
for Python asyncio
With Python's `match`, frozen dataclasses, and `type` unions, it reads close to
the Scala DSL:
```python
@dataclass(frozen=True)
class Increment:
by: int
@dataclass(frozen=True)
class GetTotal:
reply_to: ActorRef[int]
type Command = Increment | GetTotal
def counter(total: int = 0) -> Behavior[Command]:
def on_message(msg: Command) -> Behavior[Command]:
match msg:
case Increment(by):
return counter(total + by)
case GetTotal(reply_to):
reply_to.tell(total)
return Behaviors.same
return Behaviors.receive_message(on_message)
```
