Enum Backoff 

pub enum Backoff {
    None,
    Fixed {
        delay: Duration,
    },
    Exponential {
        initial: Duration,
        max: Duration,
        jitter: f64,
    },
}

Backoff strategy between retry attempts.

Variants

None

No delay between retries (immediate retry on timeout).

This is the default for backward compatibility. Consider using Backoff::Exponential for production use to avoid overwhelming agents under load.

Fixed

Fixed delay between each retry attempt.

Fields

delay: Duration

Delay before each retry

Exponential

Exponential backoff: delay doubles after each attempt.

With jitter enabled (recommended), the actual delay is randomized within a range to prevent synchronized retries from multiple clients.

Fields

initial: Duration

Initial delay before first retry

max: Duration

Maximum delay cap

jitter: f64

Jitter factor (0.0-1.0). E.g., 0.25 means ±25% randomization.
