Struct NatTraversalMetrics 

pub struct NatTraversalMetrics {
    pub hole_punch_attempts: u64,
    pub hole_punch_successes: u64,
    pub hole_punch_failures: u64,
    pub relay_connections: u64,
}

NAT traversal (hole-punching) metrics

Tracks the outcome of DCUtR hole-punch attempts so operators can assess whether relay fallback is being relied on too heavily.

Fields

hole_punch_attempts: u64

Total number of hole-punch attempts initiated (both sides)

hole_punch_successes: u64

Hole-punch attempts that resulted in a direct connection

hole_punch_failures: u64

Hole-punch attempts that failed (connection remained via relay)

relay_connections: u64

Number of connections currently established via a relay circuit

Implementations

impl NatTraversalMetrics

pub fn success_rate(&self) -> f32

Fraction of hole-punch attempts that succeeded (0.0 if no attempts).
