Timer
super simple header-only c++ timer that you can add to any project.
Demo
clone this repo, and run
g++ -o demo demo.cpp
./demo
Simple Usage
Just add timer.hpp to a include location.
Requires C++17.
To time a code block, create the timer:
{
timer::Timer myTimer();
//
// lots of code
//
}
This will print the timing when myTimer goes out of scope.
It uses std::chrono::high_resolution_clock for the timing.
More Features
You can set some optional parameters when constructing myTimer
std::string name = "myTimer"; // default is "timer"
bool print_on_exit = false ; // default is true
timer::Timer myTimer(name, print_on_exit)
If print_on_exit is true, the time taken will be printed to std::cout when myTimer is deleted.
To get the time at a specific point in your code,
uint64_t ms = myTimer.elapsed_ms() // to get the duration in milliseconds
uint64_t us = myTimer.elapsed_us() // to get the duration in microseconds
uint64_t mins = myTimer.elapsed<std::chrono::minutes>(); // to get the duration in any std::chrono::duration
You can also:
myTimer.reset() // to reset the start time
myTimer.print() // to print the current timing
myTimer.print(label) // to print the current timing with a label.
