How to schedule Jobs in the future using as async/await and job_scheduler

future_job_scheduler.rs

use async_std;
use futures_timer::Delay;
use job_scheduler::{Job, JobScheduler};
use std::time::Duration;

#[async_std::main]
async fn main() {
    let a = async { 1u8 };
    let b = a.await;
    let mut sched = JobScheduler::new();

    sched.add(Job::new("* * * * * *".parse().unwrap(), || {
        println!("I get executed every second!");
    }));
    
    sched.add(Job::new("1/5 * * * * *".parse().unwrap(), || {
        println!("I get executed every 5 seconds!");
    }));

    loop {
        sched.tick();
        let time_till_next_job = sched.time_till_next_job();
        Delay::new(time_till_next_job).await;
        // Not needed
        // std::thread::sleep(Duration::from_millis(50));
    }
}
