Examples

use exec_duration::ExecProbe;

fn function_1() {
    // Create a new execution probe object
    // exec duration will be computed from this point
    let mut ep = ExecProbe::new("function_1");

    // some code

    // add a new point
    ep.add_point("part 1");

    // some code

    // add a new point
    ep.add_point("part 2");

    // some code

    // add a new point
    ep.add_point("part 3");
}

fn function_2() {
    // Create a new execution probe object
    // exec duration will be computed from this point
    let mut ep = ExecProbe::new("function_2");

    // some code

    // add a new point
    ep.add_point("part 1");

    // some code

    // add a new point
    ep.add_point("part 2");

    // some code

    // optionally call the stop function
    ep.stop();
}

fn main() {
    function_1();
    function_2();

    // fetch results
    if let Ok(list) = exec_duration::fetch_results() {
        for r in list.iter() {
            println!("{}", r);
        }
    }
