Struct TimestampTracker 

pub struct TimestampTracker { /* private fields */ }

Available on crate feature transport only.

Timestamp tracker for RTT measurement via timestamp echo.

Each frame carries a timestamp and echoes the peer’s timestamp. When we receive an echo of our timestamp, we can compute RTT.

Implementations

impl TimestampTracker

pub fn new() -> Self

Create a new timestamp tracker.

pub fn with_start(start: Instant) -> Self

Create a timestamp tracker with a specific start time.

pub fn now(&self) -> u32

Get the current timestamp (ms since session start).

pub fn timestamp_echo(&self) -> u32

Get the timestamp echo value (peer’s last timestamp).

pub fn on_send(&mut self, timestamp: u32)

Record that we’re sending a frame with the given timestamp.

pub fn on_receive(&mut self, peer_timestamp: u32, echo: u32) -> Option<Duration>

Process a received frame’s timestamps.

Returns an RTT sample if the echo matches our pending timestamp.

pub fn clear_pending(&mut self)

Clear the pending timestamp (e.g., on retransmission).

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

Formats the value using the given formatter.

impl Default for TimestampTracker

fn default() -> Self
