Enum BackoffStrategy 

pub enum BackoffStrategy {
    None,
    Fixed {
        delay: Duration,
    },
    Linear {
        base: Duration,
        max: Duration,
    },
    Exponential {
        base: Duration,
        multiplier: f64,
        max: Duration,
    },
}

Backoff strategy for computing delay between retry attempts.

Variants

None

No delay between retries.

Fixed

Fixed delay between all retries.

Fields

delay: Duration

Delay duration between each retry.

Linear

Linear backoff: delay = base * attempt, capped at max.

Fields

base: Duration

Base delay multiplied by attempt number.

max: Duration

Maximum delay cap.

Exponential

Exponential backoff: delay = base * multiplier^(attempt-1), capped at max.

Fields

base: Duration

Initial delay for first retry.

multiplier: f64

Multiplier applied each attempt.

max: Duration

Maximum delay cap.

Implementations

impl BackoffStrategy

pub fn delay_for_attempt(&self, attempt: u32) -> Duration

Compute delay for given attempt (1-indexed). Attempt 1 is after first failure, so delay_for_attempt(1) is the first backoff.

Trait Implementations

impl Clone for BackoffStrategy

fn clone(&self) -> BackoffStrategy

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BackoffStrategy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for BackoffStrategy

fn default() -> Self

Returns the “default value” for a type.
