Enum Backoff 

pub enum Backoff {
    None,
    Fixed(Duration),
    Exponential {
        base: Duration,
        factor: u32,
        max: Duration,
    },
}

Backoff strategy between retry attempts.

Variants

None

Retry immediately.

Fixed(Duration)

Wait a fixed duration before each retry.

Exponential

base * factor^(attempt-1), capped at max.

Fields

base: Duration

factor: u32

max: Duration
