Use the Job trait to create your cron job struct, pass it to the Runner and then start it via run() method.
Runner will spawn new thread where it will start looping through the jobs and will run their handle
method once the scheduled time is reached.
If your OS has enough threads to spare each job will get its own thread to execute, if not it will be executed in the same thread as the loop but will hold the loop until the job is finished.
Please look at the Job trait documentation for more information.
```rust extern crate crony;
use crony::{Job, Runner, Schedule}; use std::str::FromStr;
struct ExampleJob; impl Job for ExampleJob { fn schedule(&self) -> Schedule { // Runs every minute Schedule::from_str("0 * * * * *").unwrap() } fn handle(&self) { println!("Hello, I am cron job running at: {}", self.now()); } }
fn main() { println!("Hello world"); Runner::new().add(Box::new(ExampleJob)).run(); }
/* Hello world Hello, I am cron job running at: 2020-12-10 16:01:59.740944 UTC Hello, I am cron job running at: 2020-12-10 16:02:59.821043 UTC */ ```
