Struct MdnsService 

pub struct MdnsService { /* private fields */ }

Long-running mDNS service with discovery, caching, and service registration.

Implementations

impl MdnsService

pub async fn new() -> Result<Arc<Self>>

Create a new mDNS service.

Call subscribe on the returned handle to receive discovery events. Multiple independent subscribers may receive events concurrently.

pub fn subscribe(&self) -> Receiver<MdnsEvent>

Subscribe to discovery events.

Returns an independent [broadcast::Receiver]; each subscriber receives every event. Subscribe before calling active_lookup to avoid missing responses that arrive before the next recv() call. On lag (RecvError::Lagged), log a warning and keep draining — events are recoverable by re-issuing active_lookup.

pub async fn add_query(&self, label: &str, qtype: u16, interval: Duration)

Add a periodic query. The query will be sent immediately, then every interval.

pub async fn remove_query(&self, label: &str)

Remove a periodic query by label.

pub async fn register_service(&self, reg: ServiceRegistration)

Register a local service to be advertised.

pub async fn unregister_service(&self, instance: &str, service_type: &str)

Unregister a local service. Sends a goodbye (TTL=0) for the service records.

pub async fn announce(&self)

Send a gratuitous announcement of all registered services.

pub async fn lookup(&self, name: &str, qtype: u16) -> Vec<RR>

Lookup cached records by name and type.

pub async fn active_lookup(&self, name: &str, qtype: u16)

pub fn shutdown(&self)

Shut down all background tasks.
