}

Available on crate feature retry only.

Backoff strategy for retries.

Variants

None

No delay between retries.

Constant(Duration)

Constant delay between retries.

Linear

Linear backoff: delay increases linearly.

Fields

initial: Duration

Initial delay.

increment: Duration

Increment per attempt.

max: Duration

Maximum delay.

Exponential

Exponential backoff: delay doubles each attempt.

Fields

initial: Duration

Initial delay.

max: Duration

Maximum delay.

multiplier: f64

Multiplier (typically 2.0).
