Add generic typing to Arrowbic base extension type #17

Open balancap opened 2 years ago

balancap commented 2 years ago

Adding generic typing is improving the general code quality, as well as, making usability of the library better in common IDEs (VS code, ...)

Currently blocked by issue in PyArrow implementation: it does not support generic extension type, i.e.


TItem = TypeVar("TItem")

class BaseExtensionType(pa.ExtensionType, Generic[TItem]):
    pass

will lead a failure when calling pa.ExtensionArray.from_storage factory method.

Implementing the generic feature only for ExtensionArray at the moment, in #18
