Struct VirtualClock 

pub struct VirtualClock { /* private fields */ }

Implementations

impl VirtualClock

pub fn new() -> Self

pub fn update( &mut self, mono: f64, offset: f64, skew_ppm: Option<f64>, error_bound: f64, )

Feed a fresh measurement.

• mono — monotonic seconds now.
• offset — seconds to ADD to the raw wall clock, measured now.
• skew_ppm — raw clock frequency error if known.
• error_bound — measurement error, seconds.

pub fn now(&mut self, mono: f64, raw_wall: f64) -> f64

Corrected wall time. raw_wall is the platform clock reading at the same instant mono was read.

pub fn confidence(&self, mono: f64) -> f64

Current error bound, seconds — grows while no updates arrive. INFINITY until the first update: callers gate decisions on this, so it must not pretend precision it does not have.

pub fn is_synchronized(&self) -> bool
