Chore/fix type hints and general clarity #57
Conversation
… files - Updated type hints for methods in context, handler, server_context, and service modules to improve type safety and clarity. - Removed unnecessary `# type: ignore` comments where type hints are now correctly specified. - General code cleanup for better readability and maintainability.

…tness issues, as the method is not currently utilized elsewhere.
…server_context modules - Updated the __await__ method signatures in RestateDurableFuture and ServerDurableFuture to specify return types as typing.Generator. - Changed the state_keys method return type in ServerInvocationContext to RestateDurableFuture[List[str]] for improved type safety. - Refined the create_df method to handle various notification types and added detailed docstring for clarity. - Ensured consistent handling of notification types across methods in ServerInvocationContext.

Hey @ouatu-ro,
thanks a lot for taking this chore, very much appreciated.
I'm afraid you'd need to rebase one more time, as i had to make some changes today, as i've discovered some issues and refactored a bit to make the whole futures handling way more robust.
Some of the code that you've annotated doesn't exists anymore.

Really good and helpful work @ouatu-ro, thank you for taking the time to adopt the type annotations etc'.
There are two or 3 comments I've left that i'd kindly like to ask you to address.
And then LGTM!

Not sure about this check. I'd need to review this in depth, can you please revert this check back for now?

Currently the function runs serde.deserialize on any object, I made it so it runs deserialisation only on bytes. will rewrite it to this for clarity:
if res is None or serde is None:
return res
if isinstance(res, bytes):
return serde.deserialize(res)
return res
Let me know if you want it changed back, but I think it would be a bug? must_take_notification should never return a JSON, it should only return str, list[str], bytes, None.

Cleared all type hint errors for better clarity.
I have also added an
assertinsidemust_take_notificationto ensure it only returnsbytesorNone.Can you confirm that this is correct? Should it not return
strorlist[str], as those are strictly associated with an invocation ID or a state keys response?
