CronTab

A cron job library for Rust.

Usage

Add cron_tab crate to your Cargo.toml:

[dependencies]
cron_tab = "0.1.0"

Creating a schedule for a job is done using the FromStr impl for the Schedule type of the cron library.

The scheduling format is as follows:

sec   min   hour   day of month   month   day of week   year
*     *     *      *              *       *             *

A simple example:

extern crate cron_tab;

use chrono::{FixedOffset, Local, TimeZone, Utc};

fn main() {
let local_tz = Local::from_offset(&FixedOffset::east(7));
let utc_tz = Utc;

let mut cron = cron_tab::Cron::new(utc_tz);

let job_test_id = cron.add_fn("* * * * * * *", test).unwrap();

cron.start();

std::thread::sleep(std::time::Duration::from_secs(2));
let anonymous_job_id = cron
.add_fn("* * * * * *", || {
println!("anonymous fn");
})
.unwrap();

// remove job_test
cron.remove(job_test_id);

loop {
std::thread::sleep(std::time::Duration::from_secs(2));
}
}

fn test() {
println!("now: {}", Local::now().to_string());
}
