Struct Server 

pub struct Server { /* private fields */ }

A simple mock server for DNS requests.

The intended usage is to create a new instance using Server::default() and add some record mappings to it. You can then bind a UdpSocket and start the server with Server::start() in a background task before making requests on the main thread.

Implementations

impl Server

pub fn add_records( &mut self, name: &str, records: Vec<IpAddr>, ) -> Result<(), ProtoError>

Adds a mapping from a DNS record to some IP addresses.

Example

let mut server = Server::default();
let records = vec![IpAddr::V4(Ipv4Addr::LOCALHOST)];

server.add_records("example.com", records).expect("Invalid hostname");

pub async fn start(self, socket: UdpSocket) -> Result<(), ProtoError>

Starts the mock server on the given UdpSocket.

This should be run in a background task using a method such as tokio::spawn.

Trait Implementations

impl Clone for Server

fn clone(&self) -> Server

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Server

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Server

fn default() -> Server

Returns the “default value” for a type.

impl RequestHandler for Server

fn handle_request<'life0, 'life1, 'async_trait, R>( &'life0 self, request: &'life1 Request, response_handler: R, ) -> Pin<Box<dyn Future<Output = ResponseInfo> + Send + 'async_trait>>

where R: 'async_trait + ResponseHandler, Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Determines what needs to happen given the type of request, i.e. Query or Update.
