Struct historian::Histo[−][src]

pub struct Histo { /* fields omitted */ }
Expand description

A histogram collector that uses zero-configuration logarithmic buckets.

Implementations

impl Histo[src]

pub fn measure<T: Into<f64>>(&self, raw_value: T) -> usize[src]

Record a value.

pub fn percentile(&self, p: f64) -> f64[src]

Retrieve a percentile [0-100]. Returns NAN if no metrics have been collected yet.

pub fn print_percentiles(&self)[src]

Dump out some common percentiles.

pub fn sum(&self) -> usize[src]

Return the sum of all observations in this histogram.

pub fn count(&self) -> usize[src]

Return the count of observations in this histogram.
