Struct RetryConfig 

pub struct RetryConfig {
    pub max_retries: u32,
    pub base_delay: Duration,
    pub max_delay: Duration,
    pub retryable_status_codes: Vec<u16>,
    pub circuit_threshold: u32,
    pub circuit_timeout: Duration,
    pub jitter: f64,
}

Retry configuration for failed requests.

Fields

max_retries: u32

Maximum number of retries

base_delay: Duration

Base delay between retries (exponential backoff)

max_delay: Duration

Maximum delay between retries

retryable_status_codes: Vec<u16>

HTTP status codes that should trigger a retry

circuit_threshold: u32

Circuit breaker: consecutive failures before opening circuit

circuit_timeout: Duration

Circuit breaker: timeout before transitioning from Open to HalfOpen

jitter: f64

Jitter factor (0.0-1.0) to add randomness to backoff delays

Implementations

impl RetryConfig

pub fn new() -> Self

Create a new retry configuration with default values.

pub fn with_max_retries(self, max_retries: u32) -> Self

Set maximum number of retries.

pub fn with_base_delay(self, delay: Duration) -> Self

Set base delay for exponential backoff.

pub fn with_max_delay(self, delay: Duration) -> Self

Set maximum delay for exponential backoff.

pub fn with_circuit_threshold(self, threshold: u32) -> Self

Set circuit breaker threshold (consecutive failures before opening).

pub fn with_circuit_timeout(self, timeout: Duration) -> Self

Set circuit breaker timeout (time before trying again).

pub fn with_jitter(self, jitter: f64) -> Self

Set jitter factor (0.0-1.0) to add randomness to backoff. This helps prevent thundering herd when services recover.

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

Calculate delay for a specific retry attempt with exponential backoff and jitter.

pub fn is_retryable(&self, status: u16) -> bool

Check if a status code should trigger a retry.

impl RetryConfig

Default retry configuration for production use. More conservative to be a good API citizen.

pub fn production() -> Self

Production-grade configuration with conservative defaults.

pub fn development() -> Self

Aggressive retry configuration for development/testing.

pub fn batch_processing() -> Self

Configuration optimized for batch processing with longer delays.

Trait Implementations

impl Clone for RetryConfig

fn clone(&self) -> RetryConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RetryConfig

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

Formats the value using the given formatter.

impl Default for RetryConfig

fn default() -> Self

Returns the “default value” for a type.
