}

Observability metrics for a mesh peer, used for affinity scoring.

Fields

node_id: String

Node identifier.

rtt_ms: f64

Smoothed round-trip time in milliseconds.

messages_sent: u64

Total messages sent to this peer.

messages_received: u64

Total messages received from this peer.

bytes_sent: u64

Total bytes sent to this peer.

bytes_received: u64

Total bytes received from this peer.

errors: u64

Total errors encountered with this peer.

last_updated: u64

Last update timestamp (epoch millis).

Implementations

impl PeerMetrics

pub fn new(node_id: String) -> Self

Create new zeroed metrics for a peer.

pub fn affinity_score(&self) -> f64

Affinity score (lower is better). Used for service resolution preference.

pub fn record_send(&mut self, bytes: u64)

Record a successful message send.

pub fn record_recv(&mut self, bytes: u64)

Record a received message.

pub fn record_error(&mut self)

Record an error.

pub fn update_rtt(&mut self, rtt_ms: f64)

Update RTT measurement using exponential moving average.
