Implementations§

Source §

impl PhaseHistogram

Source

pub fn new() -> Self

Source

pub fn record(&self, value_us: u64)

Record a single sample (microseconds). Lock-free.

Source

pub fn recent_tail_us(&self) -> u64

Return a constant-time recent tail estimate for scheduler hot paths.

Source

pub fn percentiles(&self) -> PhasePercentiles

Snapshot percentiles: returns (p50, p95, p99, max, count, mean_us).

Source

pub fn reset(&self)

Reset all samples and counters.
