DNS SIG/RRSIG rdatas apply to a specific type; this type is
returned by the covers() function. If the rdata type is not
SIG or RRSIG, dns.rdatatype.NONE is returned. This is useful when
creating rdatasets, allowing the rdataset to contain only RRSIGs
of a particular type, e.g. RRSIG(NS).

This function attempts to dynamically load a class which
implements the specified rdata class and type. If there is no
class-and-type-specific implementation, the GenericRdata class
is used.
Once a class is chosen, its from_text() class method is called
with the parameters to this function.
If *tok* is a ``text``, then a tokenizer is created and the string
is used as its input.
*rdclass*, an ``int``, the rdataclass.
*rdtype*, an ``int``, the rdatatype.
*tok*, a ``dns.tokenizer.Tokenizer`` or a ``text``.
*origin*, a ``dns.name.Name`` (or ``None``), the
origin to use for relative names.
*relativize*, a ``bool``. If true, name will be relativized to
the specified origin.
Returns an instance of the chosen Rdata subclass.

This function attempts to dynamically load a class which

is used.
Once a class is chosen, its from_wire() class method is called
with the parameters to this function.
*rdclass*, an ``int``, the rdataclass.
*rdtype*, an ``int``, the rdatatype.
*wire*, a ``binary``, the wire-format message.
*current*, an ``int``, the offset in wire of the beginning of
the rdata.
*rdlen*, an ``int``, the length of the wire-format rdata
*origin*, a ``dns.name.Name`` (or ``None``). If not ``None``,
then names will be relativized to this origin.
Returns an instance of the chosen Rdata subclass.
