dig_nat::method

Struct MethodOutcome 

Source 
pub struct MethodOutcome {
    pub kind: TraversalKind,
    pub dial_addrs: Vec<SocketAddr>,
}
Expand description

What a traversal method yields on success: the dialable candidate addresses for the peer (ordered IPv6-first), plus which technique produced them. The crate::strategy then performs the mTLS dial, trying the candidates IPv6-first with IPv4 fallback (happy-eyeballs, see crate::dialer) — except the relayed method, which returns the already-open relay tunnel.

The direct/mapping methods carry the peer’s whole IPv6-first candidate list so the dial can fall back across families; the hole-punch/relayed methods yield a single coordinated/relay address (MethodOutcome::single).

Fields§

§kind: TraversalKind

Which technique produced these reachable addresses.

§dial_addrs: Vec<SocketAddr>

The candidate addresses the strategy should dial, ordered IPv6-first (peer public endpoints, a hole-punched peer address, the relay endpoint, or — mapping methods — the peer candidates to try after opening the local pinhole). The dialer tries them IPv6-first and falls back to IPv4. Never empty on success.

Implementations§

Source§

impl MethodOutcome

Source

pub fn single(kind: TraversalKind, dial_addr: SocketAddr) -> Self

An outcome carrying a SINGLE dial address (hole-punch / relayed tiers, which yield one coordinated peer address or the relay endpoint).

Source

pub fn candidates(kind: TraversalKind, dial_addrs: Vec<SocketAddr>) -> Self

An outcome carrying the peer’s ordered candidate list (direct / mapping tiers). The addresses are (re-)sorted IPv6-first so the dial honours the fallback order regardless of input order.

Source

pub fn dial_addr(&self) -> Option<SocketAddr>

The single best (IPv6-preferred) dial address — the first candidate — or None if empty.
