Struct NatConfig 

Source 
pub struct NatConfig {
    pub enabled_methods: Vec<TraversalKind>,
    pub per_method_timeout: Duration,
    pub relay_endpoint: String,
    pub stun_server: Option<SocketAddr>,
}
Expand description

Which traversal methods are enabled + the per-method deadline and relay settings for a connect.

The DEFAULT enables every method in the canonical order with sane timeouts and the canonical dig_constants::DIG_RELAY_URL relay. The caller tweaks via the builder but never picks which method wins — the strategy does, first-success-wins, relay-last.

Fields§

§enabled_methods: Vec<TraversalKind>

The traversal techniques permitted, by kind. The strategy always tries them in TraversalKind::rank order regardless of the order here.

§per_method_timeout: Duration

Per-method hard timeout — a method that does not complete in this window is abandoned and the strategy moves on (this is the guarantee that a hung method can never block connect).

§relay_endpoint: String

The relay WebSocket endpoint for the relay-coordinated + relayed methods. Defaults to the canonical relay; honour the DIG_RELAY_URL env override / =off opt-out via crate::relay::relay_url_from_env / crate::relay::relay_enabled.

§stun_server: Option<SocketAddr>

A STUN server used to discover this node’s reflexive address for candidate advertisement + hole-punch. None = derive from the relay host on the standard STUN port STUN_PORT (the relay co-locates a STUN server, L7 spec §3): point a node at a private relay and its STUN follows.
