Struct StaleClock 

pub struct StaleClock { /* private fields */ }

Elapsed time over a dump stream, for parsers that drop state a connection or dialog has stopped feeding.

A dated timestamp gives absolute seconds from its own date. A time-only timestamp has no date, so it gets a synthetic day counter that increments when the clock wraps past midnight. The two carry no common epoch: a stream that changes format resets the clock, and the sweep that would follow that reset is skipped, since every recorded time then belongs to the other domain.

Implementations

impl StaleClock

pub const TIMEOUT_SECS: u64 = 7200

How long a connection or dialog may stay silent before its pending state is dropped: the RFC 793 default TCP keepalive timeout, beyond which a VoIP connection is dead.

pub fn new() -> Self

A clock that has seen no timestamp yet.

pub fn observe(&mut self, timestamp: Timestamp) -> u64

Record a timestamp and return the stream time it reads, in seconds.

pub fn now(&self) -> u64

The stream time of the last observed timestamp, in seconds.

pub fn sweep_due(&mut self) -> bool

Whether a stale sweep is due, marking one as taken when it is. The first sweep after a format change is not due: no recorded time is comparable to the clock’s new domain.

pub fn is_stale(&self, last_seen: u64) -> bool

Whether a time recorded from now has gone stale.
