Struct UtcClock 

pub struct UtcClock { /* private fields */ }

The clock: at most one anchor.

Implementations

impl UtcClock

pub fn new() -> Self

A clock with no anchor.

pub fn anchor(&self) -> Option<&Anchor>

The current anchor.

pub fn utc_at(&self, now_us: u64) -> Option<i64>

UTC at now_us, or None before the first anchor.

pub fn mono_for_utc(&self, utc_us: i64) -> Option<u64>

The monotonic instant at which UTC reaches utc_us.

pub fn offer( &mut self, sample: UtcSample, source: ClockSource, now_us: u64, policy: OfferPolicy, ) -> OfferOutcome

Offer a measurement; the anchor changes per the replacement rule.

A more trusted source replaces at once; a less trusted one only when policy.allow_downgrade. For the same source: a reading that disagrees with the prediction by more than the two error bars together is a clock step and is adopted immediately; otherwise it replaces the anchor when it is at least as precise or the anchor is older than policy.resync_us.
