A helper trait allowing construction of records on the fly.

The trait’s primary users arer the three record section buider type of the [message builder] system. Their push methods accept anything that implements this trait.

Implementations are provided for Record values and references. In addition, a tuple of a domain name, class, TTL, and record data can be used as this trait, saving the detour of constructing a record first. Since the class is pretty much always Class::In, it can be left out in this case.

Required Associated Types

type Name: ToDname

The type of the record’s owner domain name.

type Data: RecordData

The type of the record data.

Required Methods

fn owner(&self) -> &Self::Name

Returns a reference to the owner domain name.

fn class(&self) -> Class

Returns the record’s class.

fn ttl(&self) -> u32

Returns the record’s TTL:

fn data(&self) -> &Self::Data

Returns a reference to the record data.

Provided Methods

fn compose_record<T: OctetsBuilder + AsMut<[u8]>>( &self, target: &mut T ) -> Result<(), ShortBuf>

Produces the encoded record.

fn compose_record_canonical<T: OctetsBuilder + AsMut<[u8]>>( &self, target: &mut T ) -> Result<(), ShortBuf>

Produces the canonically encoded record.
