Trait BackoffStrategy

pub trait BackoffStrategy<'a, E> {
    type Output;

    // Required method
    fn delay(&mut self, attempt: u32, error: &'a E) -> Self::Output;
}

Trait for computing the amount of delay between attempts.

Required Associated Types

type Output

The delay type. Will normally be either Duration or RetryPolicy.

Required Methods

fn delay(&mut self, attempt: u32, error: &'a E) -> Self::Output

Compute the amount of delay given the number of attempts so far and the most previous error.
