Implementations

impl StunClient

pub fn new(stun_server: SocketAddr) -> Self

A constructor with default parameters

pub fn with_google_stun_server() -> Self

Use hard coded STUN server stun.l.google.com:19302.

Not for production use, for tests, prototypes and demos. May block the thread. May panic in case of address resolution problems.

pub fn set_timeout(&mut self, timeout: Duration) -> &mut Self

Set timeout field, builder pattern.

pub fn set_retry_interval(&mut self, retry_interval: Duration) -> &mut Self

Set retry_interval field, builder pattern.

pub fn set_software(&mut self, software: Option<&'static str>) -> &mut Self

Set software field, builder pattern.

impl StunClient

pub fn query_external_address( &self, udp: &UdpSocket, ) -> Result<SocketAddr, Error>

Get external (server-reflexive transport address) IP address and port of specified UDP socket

pub async fn query_external_address_async( self, udp: &UdpSocket, ) -> Result<SocketAddr, Error>

async version of query_external_address.

Requires async crate feature to be enabled (it is by default)
