Struct Calibration 

pub struct Calibration {
    pub ns_per_tick: u64,
    pub frac: u32,
    pub method: CalMethod,
}

A calibrated ns-per-tick conversion factor, held as ns_per_tick + frac/2^32 (a 32.32 fixed point).

Conversion (Calibration::ticks_to_ns) is two multiplies and a shift — no division on the read path. REQ-CLK-003.

Fields

ns_per_tick: u64

Integral nanoseconds per counter tick.

frac: u32

Fractional nanos per tick, numerator over 2^32.

method: CalMethod

How the factor was measured.

Implementations

impl Calibration

pub fn ticks_to_ns(&self, ticks: u64) -> u64
