Struct SimpleMdnsResponder 

pub struct SimpleMdnsResponder { /* private fields */ }

A simple mDNS responder aimed for service discovery. In case you don’t have a mDNS responder in your network, or for some reason don’t want to use the ones available.

This responder will list for any mDNS query in the network via Multicast and will reply only to the resources that were added.

    use simple_mdns::sync_discovery::SimpleMdnsResponder;
    use simple_dns::{Name, CLASS, ResourceRecord, rdata::{RData, A, SRV}};
    use std::net::Ipv4Addr;


    let mut responder = SimpleMdnsResponder::new(10);
    let srv_name = Name::new_unchecked("_srvname._tcp.local");

    responder.add_resource(ResourceRecord::new(
        srv_name.clone(),
        CLASS::IN,
        10,
        RData::A(A { address: Ipv4Addr::LOCALHOST.into() }),
    ));

    responder.add_resource(ResourceRecord::new(
        srv_name.clone(),
        CLASS::IN,
        10,
        RData::SRV(SRV {
            port: 8080,
            priority: 0,
            weight: 0,
            target: srv_name
        })
    ));

This struct heavily relies on simple_dns crate and the same must be added as a dependency
