Enum BackoffStrategy 

pub enum BackoffStrategy {
    Constant(Duration),
    Linear {
        base: Duration,
    },
    Exponential {
        base: Duration,
        max: Duration,
    },
    Fibonacci {
        base: Duration,

}

Backoff strategy for retry delays.

Variants

Constant(Duration)

Constant delay between retries.

Linear

Linearly increasing delay: base * attempt.

Fields

base: Duration

Base delay multiplied by the attempt number.

Exponential

Exponentially increasing delay: base * 2^attempt, capped at max.

Fields

base: Duration

Initial delay.

max: Duration

Maximum delay cap.

Fibonacci

Fibonacci-sequence based delay: fib(attempt) * base.

Fields

base: Duration

Base unit of delay.
