Crate hdrhistogram

Rust binding for HdrHistogram_c

This crate implements bindings for HdrHistogram_c, a flexible library for recording histograms without having to know very much about the data being histogrammed.

The top-level type is Histogram.

Example

This sets up a histogram to record values in the range 1..1000_000 with 2 significant figures of precision. It then records one count each of 1 and 10, and 40 counts of 100.

let mut h = Histogram::init(1, 1000000, 2).unwrap();
 
h.record_value(1);
h.record_value(10);
h.record_values(100, 40);

assert_eq!(h.total_count(), 42);
assert_eq!(h.min(), 1);
assert_eq!(h.max(), 100);
