## A Cron Expression Parser in Rust

```rust
extern crate cron;
extern crate chrono;

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);
  }
}

/*
