Crate retry_fn 

retry

Function for executing retry either as a closure with a std-based sleep (thread::sleep) or using either of the most popular async runtimes. See tokio or async-std module for futures-aware versions.

Sync Example

use retry_fn::{retry, RetryResult, strategy::ExponentialBackoff};
let mut count = 0;
let res = retry(ExponentialBackoff::new(Duration::from_secs(2)), |op| {
   if op.retries >= 3 {
       RetryResult::<&str, _>::Err(io::Error::new(
           io::ErrorKind::TimedOut,
           "timed out",
       ))
   } else {
       count += 1;
       RetryResult::Retry()
   }
});
assert_eq!(count, 3);
assert!(res.is_err());
Ok(())
