Enum RetryPolicy

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

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

Variants§

§

Repeat

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.

§

WaitRetry(Duration)

Wait for a given duration and make another attempt then.

§

ForwardError(E)

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

fn ne(&self, other: &Rhs) -> bool
