Specification and Check of Data Type of the attribute

[fhaselbeck]

Hi,

this is a very useful feature, thanks a lot for your work!
It would be great if there would also be the functionality to specify the data type of the attribute that needs to be implemented.

Do you have any ideas on that?

Thanks and kind regards
Florian

Try this, it seems to be working for me

class Animal( metaclass=ABCMeta):
  @abstract_attribute
  def edible(self) -> list[str]|None:
    pass

Though, I would like to avoid the |None.
