Struct MessageResponseBuilder 

pub struct MessageResponseBuilder<'q> { /* private fields */ }

A builder for MessageResponses

Implementations

impl<'q> MessageResponseBuilder<'q>

pub fn new(queries: &'q Queries, edns: Option<&'q Edns>) -> Self

Constructs a new response builder

Arguments

• queries - queries (from the Request) to associate with the Response
• edns - Optional Edns data to associate with the Response

pub fn from_message_request(message: &'q MessageRequest) -> Self

Constructs a new response builder

Arguments

• message - original request message to associate with the response

Example

use hickory_proto::{op::ResponseCode, rr::Record};
use hickory_server::{
    server::Request,
    zone_handler::{MessageResponse, MessageResponseBuilder},
};

fn handle_request<'q>(request: &'q Request) -> MessageResponse<
    'q,
    'static,
    impl Iterator<Item = &'static Record> + Send + 'static,
    impl Iterator<Item = &'static Record> + Send + 'static,
    impl Iterator<Item = &'static Record> + Send + 'static,
    impl Iterator<Item = &'static Record> + Send + 'static,
> {
    MessageResponseBuilder::from_message_request(request)
        .error_msg(&request.metadata, ResponseCode::ServFail)
}

pub fn edns(&mut self, edns: &'q Edns) -> &mut Self

Associate EDNS with the Response

pub fn build<'a, A, N, S, D>( self, metadata: Metadata, answers: A, authorities: N, soa: S, additionals: D, ) -> MessageResponse<'q, 'a, A::IntoIter, N::IntoIter, S::IntoIter, D::IntoIter>

where A: IntoIterator<Item = &'a Record> + Send + 'a, A::IntoIter: Send, N: IntoIterator<Item = &'a Record> + Send + 'a, N::IntoIter: Send, S: IntoIterator<Item = &'a Record> + Send + 'a, S::IntoIter: Send, D: IntoIterator<Item = &'a Record> + Send + 'a, D::IntoIter: Send,

Constructs the new MessageResponse with associated data

pub fn build_no_records<'a>( self, metadata: Metadata, ) -> MessageResponse<'q, 'a, impl Iterator<Item = &'a Record> + Send + 'a, impl Iterator<Item = &'a Record> + Send + 'a, impl Iterator<Item = &'a Record> + Send + 'a, impl Iterator<Item = &'a Record> + Send + 'a>

Construct a Response with no associated records

pub fn error_msg<'a>( self, request_meta: &Metadata, response_code: ResponseCode, ) -> MessageResponse<'q, 'a, impl Iterator<Item = &'a Record> + Send + 'a, impl Iterator<Item = &'a Record> + Send + 'a, impl Iterator<Item = &'a Record> + Send + 'a, impl Iterator<Item = &'a Record> + Send + 'a>

Constructs a new error MessageResponse with associated header and response code
