Thank you for opening a Pull Request! Before submitting your PR, there are a few things you can do to make sure it goes smoothly:

  • Make sure to open an issue as a bug/issue before writing your code! That way we can discuss the change, evaluate designs, and agree on the general idea
  • Ensure the tests and linter pass
  • Code coverage does not decrease (if any source code was changed)
  • Appropriate docs were updated (if necessary)

Fixes #266 🦕

Good call, done.

I probably could have used Dict[str, Any] like we did here for dtypes, but maybe something more specific would be better?

Note: we aren't currently running any sort of type checking in this repo. There's an open issue for it here: #325

For a start, Dict[str, any] is probably just fine, especially if type checks are not implemented yet. Let's just make sure it's consistent with the docstring, the latter currently says Optional[Map[str, Union[str, pandas.Series.dtype]]].

LGTM.

The two comments are non-blocking.
(making the annotation consistent with the docstring and excluding the TYPE_CHECKING imports from coverage)

This will never be executed during the tests (TYPE_CHECKING is False at runtime), thus at some point coverage will complain. Let's add a # pragma: NO COVER comment to ignore this block.
