Task

```rust extern crate scron; use scron::Task; use scron::Tasks;

fn main() { let task = Task::new("test".to_owned(), "0/3 * * * * *", || { println!("haha"); });

let mut tasks = Tasks { task: vec![task] };

tasks.run();

} ```

scron

```rust extern crate scron; extern crate chrono;

use scron::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); } }

/* Upcoming fire times: -> 2018-06-01 09:30:00 UTC -> 2018-06-01 12:30:00 UTC -> 2018-06-01 15:30:00 UTC -> 2018-06-15 09:30:00 UTC -> 2018-06-15 12:30:00 UTC -> 2018-06-15 15:30:00 UTC -> 2018-08-01 09:30:00 UTC -> 2018-08-01 12:30:00 UTC -> 2018-08-01 15:30:00 UTC -> 2018-08-15 09:30:00 UTC */ ```
