Enum RetryPolicy 

pub enum RetryPolicy<E = String> {
    Retry(Option<Error>),
    Fail(E),
}

Return type of inner future inside RetryFuture

Fail variant means unrecoverable error

If future propagates errors early by using ? then Retry will contain error inside it.

If you want to provide some debug information about why a Future failed, you can construct error youself.

Variants

Retry(Option<Error>)

Fail(E)

Unrecoverable error which means that the RetryFuture Future will immediately return with an error
