cron 
A cron expression parser. Works with stable Rust v1.28.0.
use cron::Schedule;
use chrono::Utc;
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(Utc).take(10) {
println!("-> {}", datetime);
}
}
