Examples

extern crate tokio_core;
extern crate tokio_retry;

use tokio_core::reactor::Core;
use tokio_retry::Retry;
use tokio_retry::strategy::{ExponentialBackoff, jitter};

fn action() -> Result<u64, ()> {
    // do some real-world stuff here...
    Ok(42)
}

fn main() {
    let mut core = Core::new().unwrap();

    let retry_strategy = ExponentialBackoff::from_millis(10)
        .map(jitter)
        .take(3);
  
    let retry_future = Retry::spawn(core.handle(), retry_strategy, action);
    let retry_result = core.run(retry_future);

    assert_eq!(retry_result, Ok(42));
