Usage

Sample code:

use cron_sched::{Cron, CronJob};

struct GreetingJob {}

impl CronJob for GreetingJob {
    fn run(&mut self) {
        println!("GreetingJob: Hello, world!")
    }
}

struct CounterJob {
    i: u64
}

impl CronJob for CounterJob {
    fn run(&mut self) {
        self.i += 1;
        println!("CounterJob: i = {}", self.i);
    }
}

fn main() {
    let mut cron = Cron::new();
    let mut greeting_job = GreetingJob {};
    let mut counter_job = CounterJob { i: 0 };

    cron.add("*/3 * * * * * *", &mut greeting_job).unwrap();
    cron.add("*/1 * * * * * *", &mut counter_job).unwrap();

    let waiting = std::time::Duration::from_millis(500u64);
    loop {
        cron.tick().unwrap();
        std::thread::sleep(waiting);
    }
}

Roadmap

• Common features
• Run method instead custom loop
• Run cron jobs in separated threads
• Add logging
• make it compatible with embedded systems (stm32)
• tokio runtime
