A simple library to help with time in rust
Chroniker has two main functions. The sleep function and the Timer API. However it also has some other utilities. One of them is the function to get the unix time.
The first, the sleep function is simply there too make sleeping simple. For instance, the next example sleeps the program for 1 second (or 1000 milliseconds).
rust
chroniker::sleep(1000);
The timer API makes timer programs very simple to time different parts of the program. To start the timer you call the timer new function. For instance:
rust
let timer = chroniker::Timer::new();
After that the timer automatically starts. To get the time you have two options. You can either print it or call the elapsedmillis() method to get the amount of milliseconds passed. Continuing on the previous example we get:
rust
println!("Timer: {:?}", timer);
let time_passed: i64 = timer.elapsed_millis();
If you want to reset the timer you will need to call the reset method like this:
rust
//Create the timer
let mut timer = chroniker::Timer::new();
//Do first operation
foo();
//Print results and then reset the timer
println!("Timer: {:?}", timer);
timer.reset();
//Do second operation
bar();
//Reprint the results
println!("Timer: {:?}", timer);
