Struct lib3h_mdns::MulticastDns

pub struct MulticastDns { /* fields omitted */ }

an mdns instance that can send and receive dns packets on LAN UDP multicast

Methods

impl MulticastDns

pub fn address(&self) -> &str

IP address of the mDNS server.

pub fn port(&self) -> u16

the mDNS service port on the machine.

pub fn multicast_loop(&self) -> bool

Returns wether multicasting is set to loop or not.

pub fn multicast_ttl(&self) -> u32

Returns the time to live value.

pub fn multicast_address(&self) -> &str

Returns the multicast address used by mDNS

pub fn records(&self) -> &MapRecord

Returns the lookup table of records as a HashMap.

pub fn own_urls(&self) -> Vec<String>

Returns a vector of all the url we own through every NetworkId.

pub fn urls(&self) -> Vec<Lib3hUri>

Returns all the urls for every NetworkId.

pub fn own_networkids(&self) -> Vec<&str>

Returns all the NetworkIds we are currently in.

pub fn query_interval_ms(&self) -> u128

Returns the amount of time we wait between two queries.

pub fn insert_own_record(&mut self, netid: &str, records: &[&str])

pub fn insert_record(&mut self, netid: &str, records: &[&str])

Insert a new record to our cache.

pub fn update_cache(&mut self, other_map_record: &MapRecord)

Update our cache of resource records.

pub fn broadcast_message(
    &self,
    dmesg: &DnsMessage
) -> Result<usize, MulticastDnsError>

Broadcasts a DNS message.

pub fn broadcast(&self, data: &[u8]) -> Result<usize, MulticastDnsError>

Broadcasts a packet.

pub fn recv(&mut self) -> MulticastDnsResult<Option<(Vec<u8>, SocketAddr)>>

try to receive a dns packet. will return None rather than blocking if none are queued

pub fn update_ttl(&mut self)

Update the time to live of every cached record.

pub fn query(&mut self) -> MulticastDnsResult<()>

mDNS Querier, implementing the "One-Shot Multicast DNS Queries" from the standard.

pub fn build_query_message(&self) -> Option<DnsMessage>

Builds a query DNS message to be used by one-shot mDNS implementation.
