jiff-cron

NOTE: these are temporary releases while waiting for the original repo to release their 0.2.0.

A cron expression parser built with jiff.

Examples

use jiff_cron::{
    jiff::tz::TimeZone,
    Schedule,
};
use std::str::FromStr;

fn main() {
    //               sec  min   hour   day of month   month   day of week   year
    let expression = "0   30   9,12,15     1,15       May-Aug  Mon,Wed,Fri  2018/2";
    let schedule = Schedule::from_str(expression).unwrap();
    println!("Upcoming fire times:");
    for datetime in schedule.upcoming(TimeZone::UTC).take(10) {
      println!("-> {}", datetime);
    }
}

/*
Upcoming fire times:
-> 2018-06-01T09:30:00+00:00[UTC]
-> 2018-06-01T12:30:00+00:00[UTC]

DST behavior

jiff also handles daylight savings gaps and folding appropriately:

use jiff_cron::{
    jiff::tz::TimeZone,
    jiff::civil::date,
    Schedule,
};
use std::str::FromStr;

fn main() {
    let expression = "0 0 * * * * *";
    let schedule = Schedule::from_str(expression).unwrap();
    let after_datetime = date(2022, 11, 5).at(23, 30, 0, 0).in_tz("America/Chicago").unwrap();
    println!("Upcoming fire times:");
    for datetime in schedule.after(&after_datetime).take(5) {
      println!("-> {}", datetime);
    }
}

/*
Upcoming fire times:
-> 2022-11-06T00:00:00-05:00[America/Chicago]
-> 2022-11-06T01:00:00-05:00[America/Chicago]
-> 2022-11-06T01:00:00-06:00[America/Chicago]
-> 2022-11-06T02:00:00-06:00[America/Chicago]
-> 2022-11-06T03:00:00-06:00[America/Chicago]
