Statistics for a link.

Fields

packets_sent: u64

Total packets sent.

packets_recv: u64

Total packets received.

bytes_sent: u64

Total bytes sent.

bytes_recv: u64

Total bytes received.

last_recv_ms: u64

Timestamp of last received packet (Unix milliseconds).

loss_rate: f32

Observed packet loss rate (0.0-1.0).

throughput_estimate: u64

Estimated throughput in bytes/second.

Implementations

impl LinkStats

pub fn new() -> Self

Create new link statistics.

pub fn record_sent(&mut self, bytes: usize)

Record a sent packet.

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

Record a received packet.

pub fn rtt_estimate(&self) -> Option<Duration>

Get the RTT estimate, if available.

pub fn update_rtt(&mut self, rtt: Duration)

Update RTT estimate from a probe response.

Uses exponential moving average with alpha=0.2.

pub fn time_since_recv(&self, current_time_ms: u64) -> u64

Time since last receive (for keepalive/timeout).

pub fn reset(&mut self)

Reset all statistics.

Trait Implementations

impl Clone for LinkStats

fn clone(&self) -> LinkStats

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LinkStats

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for LinkStats

fn default() -> LinkStats

Returns the “default value” for a type.
