Struct AnswerBuilder

pub struct AnswerBuilder { /* private fields */ }

Builds the answer section of a DNS message.

This type is typically constructed by calling answer on a MessageBuilder. See the module documentation for an overview of how to build a message.

Once acquired, you can access a message’s header or append resource records to the message’s answer section with the push method.

Implementations

impl AnswerBuilder

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 opt(self) -> Result<OptBuilder, ShortBuf>

where Self: Sized,

Proceeds to building the OPT record.

The method will start by adding the record header. Since this may exceed the message limit, the method may fail. If you have saved space for the OPT record via set_limit earlier, remember to increase the limit again before calling opt.
