Struct domain_core::bits::message_builder::AuthorityBuilder

pub struct AuthorityBuilder { /* fields omitted */ }

Builds the authority section of a DNS message.

This type can be constructed by calling authority() on a MessageBuilder or AnswerBuilder. See the module documentation for details on constructing messages.

Once acquired, you can use this type to add records to the authority section of a message via the push method.

Methods

impl AuthorityBuilder

pub fn additional(self) -> AdditionalBuilder

Proceeds to building the additional section.

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.
