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

Documentation

https://docs.rs/howlong

Usage

Add this to your Cargo.toml:

[dependencies]
howlong = "0.1"

Examples

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

let timer = howlong::ProcessCPUTimer::new();
// do other computations
println!("{}", timer.elapsed()); // 5.71s wall, 5.70s user + 0ns system = 5.70s CPU (99.8%)
