Expand description

Summary view over a Histogram.

Implementations§

Source§

impl HistogramSummary<'_>

Source

pub fn count(&self) -> u64

Returns the number of samples in the histogram.

This is adjusted by the weight of each sample, based on the sample rate given during insertion.

Source

pub fn sum(&self) -> f64

Returns the sum of all samples in the histogram.

This is adjusted by the weight of each sample, based on the sample rate given during insertion.

Source

pub fn min(&self) -> Option<f64>

Returns the minimum value in the histogram.

If the histogram is empty, None will be returned.

Source

pub fn max(&self) -> Option<f64>

Returns the maximum value in the histogram.

If the histogram is empty, None will be returned.

Source

pub fn avg(&self) -> f64

Returns the average value in the histogram.

Source

pub fn median(&self) -> Option<f64>

Returns the median value in the histogram.

If the histogram is empty, None will be returned.

Source

pub fn quantile(&self, quantile: f64) -> Option<f64>

Returns the given quantile in the histogram.

If the histogram is empty, or if quantile is less than 0.0 or greater than 1.0, None will be returned.
