CustomValidator Error: Use `not` instead of `~`

[Ghost---Shadow]

My CustomValidator returned True and False. But,

line 85: validation.py

says

simple_validation = ~self.validate(series)

Which does a bitwise not.

I think the documentation needs to be more clear about the expectation or we should change to line to.

simple_validation = not self.validate(series)

If you're using a CustomSeriesValidation (which you are evidently doing here), the documentation says that you must return a boolean Series, from your validation function, not a single boolean.

If you want to return a single boolean for each cell, you should use CustomElementValidation, or if you want to validate the whole Series as passing or failing, you can attempt to mimic IsDtypeValidation.

Incidentally, this behaviour will be much nicer in the next major version. You will be able to return a single boolean to indicate that the whole Series has passed/failed the validation, or a boolean Series which will apply for each position in the Series.
