Struct SubMsSamples 

pub struct SubMsSamples<'a> { /* private fields */ }

Borrowing facade over a sample slice. Zero-cost - holds a reference only. Lazy-sorts internally on demand for percentile queries.

Implementations

impl<'a> SubMsSamples<'a>

pub fn new(raw: &'a [u64]) -> Self

Wrap a borrowed slice of nanosecond samples.

pub fn count(&self) -> usize

Number of samples in the underlying slice.

pub fn is_empty(&self) -> bool

true if the underlying slice is empty.

pub fn raw(&self) -> &'a [u64]

Raw chronological sample buffer.

pub fn p50(&self) -> u64

50th percentile (median).

pub fn p90(&self) -> u64

90th percentile.

pub fn p99(&self) -> u64

99th percentile - the standard tail-latency headline.

pub fn p999(&self) -> u64

99.9th percentile - the “worst typical case”.

pub fn max(&self) -> u64

Maximum observed sample, 0 if empty.

pub fn mean(&self) -> u64

Arithmetic mean. 0 if empty.

pub fn stddev(&self) -> u64

Sample standard deviation (n-1).

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

Arbitrary quantile in [0.0, 1.0]. Sorts internally.

pub fn percentile_sweep( &self, start: f64, end: f64, step: f64, ) -> Vec<(f64, u64)>

Sweep across a quantile range.

pub fn cdf_buckets(&self) -> Vec<u64>

Log2-spaced CDF buckets. Only available with the histogram feature.

pub fn jitter_score(&self) -> f64

Measurement-rig jitter score in [0.0, 1.0]. Only available with the jitter feature.

pub fn conditional_tail_expectation(&self, q: f64) -> u64

Conditional tail expectation. Only with tail feature.

pub fn tail_fatness_ratio(&self) -> f64

Tail fatness ratio (p99 / p50). Only with tail feature.

pub fn hill_tail_index(&self, k: usize) -> Option<f64>

Hill estimator. Only with tail feature.

pub fn iqr(&self) -> u64

Interquartile range. Only with robust feature.

pub fn median_absolute_deviation(&self) -> u64

Median absolute deviation. Only with robust feature.

pub fn coefficient_of_variation(&self) -> f64

Coefficient of variation. Only with robust feature.

pub fn skewness(&self) -> f64

Skewness (3rd standardised moment). Only with robust feature.

pub fn kurtosis(&self) -> f64

Excess kurtosis. Only with robust feature.

pub fn bootstrap_percentile_ci( &self, q: f64, iters: usize, confidence: f64, seed: u64, ) -> (u64, u64)

Bootstrap CI for a percentile. Only with bootstrap feature.
