Struct LatencyHistogram 

pub struct LatencyHistogram { /* private fields */ }

Latency histogram for tracking operation latencies

Implementations

impl LatencyHistogram

pub fn new() -> Self

Create a new latency histogram with default buckets

Default buckets: [10, 50, 100, 500, 1000, 5000, 10000, 50000] microseconds

pub fn with_buckets(buckets: Vec<u64>) -> Self

Create a histogram with custom bucket boundaries

pub fn record(&mut self, latency: Duration)

Record a latency sample

pub fn avg(&self) -> Duration

Get average latency

pub fn min(&self) -> Duration

Get minimum latency

pub fn max(&self) -> Duration

Get maximum latency

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

Get percentile value (0.0 - 1.0)

Example: percentile(0.99) returns the 99th percentile latency

pub fn p50(&self) -> Duration

Get p50 (median)

pub fn p90(&self) -> Duration

Get p90

pub fn p95(&self) -> Duration

Get p95

pub fn p99(&self) -> Duration

Get p99

pub fn p999(&self) -> Duration

Get p999 (99.9th percentile)

pub fn count(&self) -> u64

Get total number of samples

pub fn summary(&self) -> String

Generate a summary report
