Struct streaming_harness_hdrhist::HDRHist

pub struct HDRHist { /* fields omitted */ }

Methods

impl HDRHist

pub fn add_value(&mut self, value: u64)

pub fn combined(self, other: Self) -> Self

impl HDRHist

pub fn new() -> Self

New HDRHist

pub fn ccdf<'a>(
    &'a self
) -> impl Iterator<Item = (u64, f64, u64)> + 'a

Output the complementary cumulative distribution function (ccdf) of the samples

Returns an iterator over increasing sample values such that, for every triple (value, prob, count), prob is the ratio of samples >= value, and count is the number of samples >= the current value and < the next value.

pub fn ccdf_upper_bound<'a>(
    &'a self
) -> impl Iterator<Item = (u64, f64)> + 'a

pub fn ccdf_lower_bound<'a>(
    &'a self
) -> impl Iterator<Item = (u64, f64)> + 'a

pub fn quantiles<'a>(
    &'a self,
    quantiles: impl Iterator<Item = f64> + 'a
) -> impl Iterator<Item = (f64, u64, u64)> + 'a

Output estimated quantiles as (quantile, lower_bound, upper_bound) pairs

Each quantile's value is somewhere >= lower_bound and < upper_bound

pub fn summary<'a>(
    &'a self
) -> impl Iterator<Item = (f64, u64, u64)> + 'a

Output a summary of estimated quantiles

pub fn summary_string(&self) -> String

Output a text summary of estimated quantiles
