Retry strategy for transient errors

Variants

NoRetry

Do not retry.

Immediate

Retry immediately up to a maximum number of attempts.

Fields

max_attempts: u32

Maximum number of retry attempts.

FixedDelay

Retry with a fixed delay between attempts.

Fields

delay: Duration

Delay between retries.

max_attempts: u32

Maximum number of retry attempts.

ExponentialBackoff

Retry with exponential backoff.

Fields

base: Duration

Base duration for backoff calculation.

max_attempts: u32

Maximum number of retry attempts.

Implementations

impl RetryStrategy

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

Compute the delay for a given retry attempt, or None if exhausted.

pub fn max_attempts(&self) -> u32

Return the maximum number of retry attempts.

Trait Implementations

impl Clone for RetryStrategy

fn clone(&self) -> RetryStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RetryStrategy

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

Formats the value using the given formatter.

impl Default for RetryStrategy

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for RetryStrategy

fn eq(&self, other: &RetryStrategy) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
