The object returned from this function will be a :py:class:`ZstdDecompressionReader` if opened for reading in binary mode, a :py:class:`ZstdCompressionWriter` if opened for writing in binary mode, or an ``io.TextIOWrapper`` if opened for reading or writing in text mode. :param filename: ``bytes``, ``str``, or ``os.PathLike`` defining a file to open or a file object (with a ``read()`` or ``write()`` method). :param mode: ``str`` File open mode. Accepts any of the open modes recognized by ``open()``. :param cctx: ``ZstdCompressor`` to use for compression. If not specified and file is opened for writing, the default ``ZstdCompressor`` will be used. :param dctx: ``ZstdDecompressor`` to use for decompression. If not specified and file is opened for reading, the default ``ZstdDecompressor`` will be used. :param encoding: ``str`` that defines text encoding to use when file is opened in text mode. :param errors: ``str`` defining text encoding error handling mode. :param newline: ``str`` defining newline to use in text mode. :param closefd: ``bool`` whether to close the file when the returned object is closed. Only used if a file object is passed.
