Expand description

Precision is a simple crate to perform measurements using hardware counters.

It is especially useful for performing micro-benchmarks.


extern crate precision;

let p = precision::Precision::new(precision::Config::default()).unwrap();

let start = p.now();

let stop = p.now();
let elapsed1 = stop - start;

let start = p.now();
let stop = p.now();
let elapsed2 = stop - start;

let elapsed_total = elapsed1 + elapsed2;
let elapsed_total_secs = elapsed_total.as_secs_f64(&p);
let hw_ticks = elapsed_total.ticks();


The difference between two timestamps.

A timestamp. Note that this is an opaque structure.
