au Convert the rdataset into DNS zone file format.
See ``dns.name.Name.choose_relativity`` for more information
on how *origin* and *relativize* determine the way names
are emitted.
Any additional keyword arguments are passed on to the rdata
``to_text()`` method.
*name*, a ``dns.name.Name``. If name is not ``None``, emit RRs with
*name* as the owner name.
*origin*, a ``dns.name.Name`` or ``None``, the origin for relative
names.
*relativize*, a ``bool``. If ``True``, names will be relativized
to *origin*.
*override_rdclass*, a ``dns.rdataclass.RdataClass`` or ``None``.
If not ``None``, use this class instead of the Rdataset's class.
*want_comments*, a ``bool``. If ``True``, emit comments for rdata
which have them. The default is ``False``.

*name*, a ``dns.name.Name`` is the owner name to use.
*file* is the file where the name is emitted (typically a
BytesIO file).
*compress*, a ``dict``, is the compression table to use. If
``None`` (the default), names will not be compressed.
*origin* is a ``dns.name.Name`` or ``None``. If the name is
relative and origin is not ``None``, then *origin* will be appended
to it.
*override_rdclass*, an ``int``, is used as the class instead of the
class of the rdataset. This is useful when rendering rdatasets
associated with dynamic updates.
*want_shuffle*, a ``bool``. If ``True``, then the order of the
Rdatas within the Rdataset will be shuffled before rendering.
Returns an ``int``, the number of records emitted.

simply shuffled.

the specified list of rdatas in text format.
*idna_codec*, a ``dns.name.IDNACodec``, specifies the IDNA
encoder/decoder to use; if ``None``, the default IDNA 2003
encoder/decoder is used.
*origin*, a ``dns.name.Name`` (or ``None``), the
origin to use for relative names.
*relativize*, a ``bool``. If true, name will be relativized.
*relativize_to*, a ``dns.name.Name`` (or ``None``), the origin to use
when relativizing names. If not set, the *origin* value will be used.
Returns a ``dns.rdataset.Rdataset`` object.
