Struct RetryPolicy 

pub struct RetryPolicy {
    pub initial_delay: Duration,
    pub max_delay: Duration,
    pub max_attempts: u32,
    pub backoff_multiplier: f64,
    pub jitter_factor: f64,
}

Retry policy configuration

Implements exponential backoff with jitter to prevent thundering herd.

Fields

initial_delay: Duration

Initial retry delay

max_delay: Duration

Maximum retry delay (caps exponential growth)

max_attempts: u32

Maximum number of retry attempts

backoff_multiplier: f64

Exponential backoff base (typically 2.0)

jitter_factor: f64

Jitter factor (0.0 to 1.0) to randomize delays

Implementations

impl RetryPolicy

pub fn new( initial_delay: Duration, max_delay: Duration, max_attempts: u32, backoff_multiplier: f64, ) -> RetryPolicy

Create a new retry policy with custom settings

pub fn transient() -> RetryPolicy

Create a policy for transient errors (aggressive retries)

pub fn severe() -> RetryPolicy

Create a policy for severe errors (conservative retries)

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

Calculate delay for a given attempt number

Uses exponential backoff with jitter: delay = base * multiplier^attempt + random_jitter

pub fn should_retry(&self, attempt: u32) -> bool

Check if we should retry based on attempt count

Trait Implementations

impl Clone for RetryPolicy

fn clone(&self) -> RetryPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RetryPolicy

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

Formats the value using the given formatter.

impl Default for RetryPolicy

fn default() -> RetryPolicy

Returns the “default value” for a type.
