Enum Backoff 

pub enum Backoff {
    Fixed(Duration),
    Exponential {
        initial: Duration,
        factor: f64,
        max: Duration,
        jitter: bool,
    },
}

Backoff strategy: how long to wait after each failure before the next attempt.

Variants

Fixed(Duration)

Fixed interval.

Exponential

Exponential backoff: initial * factor^attempt, capped at max; when jitter is on, draw full jitter in [0, computed value) (thundering-herd protection — requests failing at the same time do not all retry at the same moment).

Fields

initial: Duration

Initial wait duration.

factor: f64

Exponential factor.

max: Duration

Cap duration.

jitter: bool

Whether to use full jitter ([0, computed value), thundering-herd protection).
