A validator is typically created in one of the following two ways: - Either by overriding this class and implementing the `validate` method. - Or by passing a callable to `Validator.from_callable`. If the validation takes some time and needs to happen in a background thread, this can be wrapped in a :class:`.ThreadedValidator`. documentr rrcCsdS)z Validate the input. If invalid, this should raise a :class:`.ValidationError`. :param document: :class:`~prompt_toolkit.document.Document` instance.
