Will return a quad ``(valid?, endsOnCodePoint?, currentIndex, totalIndex)``. As soon as an octet is encountered which renders the octet sequence invalid, a quad with ``valid? == False`` is returned. ``currentIndex`` returns the index within the currently consumed chunk, and ``totalIndex`` the index within the total consumed sequence that was the point of bail out. When ``valid? == True``, currentIndex will be ``len(ba)`` and ``totalIndex`` the total amount of consumed bytes. rrr FrT)ÚlenrrÚ UTF8_REJECTrr)rÚbaÚlÚiÚstaterrrÚvalidatewsùzUtf8Validator.validateN) Ú__name__Ú __module__Ú __qualname__Ú__doc__Ú __slots__rrrr&rrrrrHs rN) Ú__all__ÚUTF8VALIDATOR_DFArr!Úwsaccel.utf8validatorrÚ ImportErrorÚbytesrÚobjectrrrrÚs  ô
