Enum futures_retry::RetryPolicy [−] [src]

pub enum RetryPolicy<E> {
    Repeat,
    WaitRetry(Duration),
    ForwardError(E),
}

What to do when a future returns an error. Used in FutureRetry::new and StreamRetry::new.

Variants

Create and poll a new future immediately.

Be careful!

Please be careful when using this variant since it might lead to a high (actually 100%) CPU usage in case a future instantly resolves into an error every time.

Wait for a given duration and make another attempt then.

Don't give it another try, just pass the error further to the user.
