Enum RetryStrategy 

pub enum RetryStrategy {
    Fixed(Duration),
    Exponential {
        initial_delay: Duration,
        max_delay: Duration,
        multiplier: f64,
    },
    Linear {
        initial_delay: Duration,
        increment: Duration,
    },
}

Backoff algorithm applied between successive RetryPolicy attempts.

Select the strategy that best matches your workload:

• RetryStrategy::Fixed — constant pause; good for idempotent operations where timing is well understood.
• RetryStrategy::Exponential — classic exponential back-off; good for transient network errors where you want to back off quickly under load.
• RetryStrategy::Linear — linear growth; a middle ground useful when a fixed number of timed steps is preferable to unbounded growth.

Variants

Fixed(Duration)

Fixed delay between retries

Exponential

Exponential backoff (delay doubles each time)

Fields

initial_delay: Duration

Delay applied before the second attempt.

max_delay: Duration

Upper bound; the delay will never grow beyond this value.

multiplier: f64

Multiplier applied to the delay on each successive failure.

Linear

Linear backoff (delay increases linearly)

Fields

initial_delay: Duration

Delay applied before the second attempt.

increment: Duration

Amount added to the delay on each successive failure.
