Expand description
A type that represents record data.
The type needs to be able to encode the record data into a DNS message
via the Compose
trait. In addition, it needs to be
able to provide the record type of a record with a value’s data via the
rtype
method.
Returns the record type associated with this record data instance.
This is a method rather than an associated function to allow one
type to be used for several real record types.
