Struct domain::bits::message_builder::AnswerBuilder

pub struct AnswerBuilder { /* fields omitted */ }

A type for building the answer section of a DNS message.

This type is typically constructed by calling answer() on a MessageBuilder. See the module documentation for details.

Methods

impl AnswerBuilder

pub fn header(&self) -> &Header

Returns a reference to the messages header.

pub fn header_mut(&mut self) -> &mut Header

Returns a mutable reference to the messages header.

pub fn push<N, D, R>(&mut self, record: R) -> ComposeResult<()> where
    N: DName,
    D: RecordData,
    R: Into<Record<N, D>>, 

Appends a new resource record to the answer section.

This method is generic over anything that can be converted into a Record. In particular, you can use four-tuples consisting of a domain name, class, TTL, and record data or triples leaving out the class which will then be assumed to be Class::In.

pub fn rewind(&mut self)

Rewinds to the beginning of the answer section.

This drops all previously assembled answer records.

pub fn authority(self) -> AuthorityBuilder

Proceeds to building the authority section.

pub fn additional(self) -> AdditionalBuilder

Proceeds to building the additional section, skipping authority.

pub fn preview(&mut self) -> &[u8]

Returns a reference to the message assembled so far.

This method requires a &mut self since it may need to update some length values to return a valid message.

In case the builder was created from a vector with previous content, the returned reference is for the full content of this vector.

pub fn finish(self) -> Vec<u8>

Finishes the message.

The resulting message will have empty authority and additional sections.
