Function futures_backoff::retry_if

pub fn retry_if<A: Action, C>(action: A, condition: C) -> RetryIf<A, C> where
    C: Condition<A::Error>, 

Run the given action, and retry on failure if the error satisfies a given condition.

Uses the default retry strategy with exponential backoff and a maximum of 5 retry attempts.

To customize the retry strategy, take a look at Strategy.

let future = retry_if(|| {
    // do some real-world stuff here...
    future::ok(42)
}, |err: &Error| err.kind() == ErrorKind::TimedOut);
