Struct U64Calibration 

pub struct U64Calibration { /* private fields */ }

Integer multiply-shift calibration for WrappingU64Duration.

Converts between raw ticks and nanoseconds using precomputed multiply-shift factors.

Implementations

impl U64Calibration

pub fn new(duration: WrappingU64Duration, duration_ns: u64) -> Self

Creates a calibration from a measured duration and its nanosecond equivalent.

pub fn new_with_reference_clock<C: Clock<Time = WrappingU64Time>, R: Clock>( clock: &C, reference_clock: &CalibratedClock<R>, min_duration: <R::Time as Time>::Duration, wait: impl FnMut(<R::Time as Time>::Instant), ) -> (Self, ClockSynchronization<R::Time, C::Time>)

Calibrates clock against reference_clock, calling wait until min_duration elapses.

Returns the calibration and a ClockSynchronization relating the two clocks to each other wait is invoked with the instant until which it should wait.

pub fn new_with_std_instant<C: Clock<Time = WrappingU64Time>>( clock: &C, min_duration: Duration, ) -> (Self, ClockSynchronization<InstantTime, C::Time>)

Calibrates clock against std::time::Instant, sleeping for at least min_duration.

This is a convenience wrapper around U64Calibration::new_with_reference_clock based on std::time::Instant and std::thread::sleep.
