Fields

count: u64

total_us: u64

min_us: u64

max_us: u64

Implementations

impl OperationStats

pub fn avg_us(&self) -> f64

Calculate average duration.

pub fn ops_per_sec(&self) -> f64

Calculate operations per second (estimate based on total time).

pub fn std_dev_us(&self) -> f64

Calculate standard deviation.

pub fn percentile(&self, p: f64) -> u64

Calculate percentile from histogram (requires sorted data).

pub fn median_us(&self) -> u64

Calculate median (P50).

pub fn p95_us(&self) -> u64

Calculate P95.

pub fn p99_us(&self) -> u64

Calculate P99.

pub fn count_below(&self, threshold_us: u64) -> u64

Count samples below threshold (for Prometheus histogram buckets).

Trait Implementations

impl Clone for OperationStats

fn clone(&self) -> OperationStats

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for OperationStats

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
