/// 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.
// The second step fails every second execution.
// Append the task to the scheduler.
scheduler.add_task(
    TaskBuilder::new(chrono::Local)
        .every("1 * * * * * *")
        .description("A simple task")
        .add_step(None, || {
            info!("Hello from step 1");
            Ok(()) // Let the scheduler know this step was a success.
        })
        .add_step(None, 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.
            }
        })
        .build(),
);

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

} ```
