howlong

This crate allows you to measure how long it takes for a program to execute in different clocks. It ports the functions of the boost-chrono and boost-timer libraries.

The following clocks and their corresponding timers are implemented.

• SystemClock, SystemTimer
• SteadyClock, SteadyTimer if supported by the system.
• HighResolutionClock, HighResolutionTimer
• ProcessRealCPUClock, ProcessRealCPUTimer
• ProcessUserCPUClock, ProcessUserCPUTimer
• ProcessSystemCPUClock, ProcessSystemCPUTimer
• ProcessCPUClock, ProcessCPUTimer
• ThreadClock, ThreadTimer

Usage

Add this to your Cargo.toml:

[dependencies]
howlong = "0.1"

Examples

use howlong::*;

let timer = HighResolutionTimer::new();
// do some computations
println!("{:?} have passed.", timer.elapsed());

let timer = ProcessCPUTimer::new();
// do other computations
println!("{}", timer.elapsed());
