Implements the :class:`codecs.Codec` protocol so that the whole-domain encoder (:func:`idna.encode`) and decoder (:func:`idna.decode`) are accessible through the standard codec machinery as ``"idna2008"``. Only the ``"strict"`` error handler is supported; any other handler raises :exc:`~idna.IDNAError`. �strict)�data�errors�returnc C s0 |dkrt d|� d���|s dS t|�t|�fS )Nr � Unsupported error handling "�"�� r )r r �len��selfr r � r �=/opt/bart/bart_venv/lib/python3.9/site-packages/idna/codec.pyr s z Codec.encodec C s0 |dkrt d|� d���|s dS t|�t|�fS )Nr r r �� r )r r r r r r r r s z Codec.decodeN)r )r ) �__name__� __module__� __qualname__�__doc__�str�tuple�bytes�intr r r r r r r s r c @ s, e Zd ZdZeeeeeef d�dd�Z dS )�IncrementalEncodera� Incremental IDNA 2008 encoder.

Any of the four Unicode label separators (``U+002E``, ``U+3002``, ``U+FF0E``, ``U+FF61``) ends a label; the result always uses ``U+002E`` as the separator.
