AttributeError: module 'mode' has no attribute 'Worker'

This must've been introduced in #24 and didn't get detected in our initial tests.

I yanked 0.3.0 immediately so that hopefully no prod environments will be affected by this issue.

I have a similar issue, importing Worker from faust

  File ".../app.py", line 5, in <module>
    from faust import App, Settings, Worker
ImportError: cannot import name 'Worker' from 'faust' (.../.venv/lib/python3.9/site-packages/faust/__init__.py)

Worked with mode-streaming 0.2.1

Is this related?

Yes it is, I'm terribly sorry you're running into this issue. Just stick with 0.2.1 for now, I'm currently working on a patch and will release 0.3.1 to fix this.
