/// A simple example of a task with two step, /// that might work or fail some times. fn main() { // Init the logger. SimpleLogger::new().init().unwrap();

// A variable to be passed in the task.
let mut exec_count = 0;

// Task scheduler with 2000ms loop frequency.
let mut scheduler = TaskScheduler::new(2000, chrono::Local);

// Create a task with 2 steps and add it to the scheduler.
let mut task = Task::new("1 * * * * * *",
                         Some("A simple task"),
                         None,
                         chrono::Local);
// A normal step 1.
task.add_step(Some("Step 1"), || {
    info!("Hello from step 1");
    Ok(()) // Let the scheduler know this step was a success.
});
// A step 2 that can fail some times.
task.add_step(Some("Step 2"), move || {
    if exec_count % 2 == 0 {
        error!("Oh no this step failed!");
        exec_count += 1;
        Err(()) // Indicate that this step was a fail.
    } else {
        info!("Hello from step 2");
        exec_count += 1;
        Ok(()) // Indicate that this step was a success.
    }
});

// Append the task to the scheduler.
scheduler.add_task(task);

// Execute the scheduler.
scheduler.run();

} ```
