Struct RetryConfig 

pub struct RetryConfig {
    pub max_retries: u32,
    pub initial_delay: Duration,
    pub max_delay: Duration,
    pub multiplier: f64,
    pub jitter: JitterKind,
    pub jitter_ratio: f64,
}

Exponential backoff retry parameters.

Adapters consume this configuration to drive retry loops. The struct itself is pure data; the actual sleep call is left to the adapter (which has access to tokio::time).

Fields

max_retries: u32

Maximum number of retry attempts after the first failure.

initial_delay: Duration

Initial delay between attempts.

max_delay: Duration

Maximum delay (caps the exponential growth).

multiplier: f64

Multiplier applied to the delay after each failure.

jitter: JitterKind

Jitter strategy to add randomness and avoid thundering herd.

jitter_ratio: f64

Jitter ratio for Uniform jitter (0.0-1.0). Default 0.25 = ±25%.

Implementations

impl RetryConfig

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

Compute the base delay for a given attempt number (0-indexed).

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

Compute the delay with jitter for a given attempt number (0-indexed).

Uses rand crate when available, falls back to a simple deterministic hash-based jitter for no-std / no-rand environments.

impl RetryConfig

pub fn with_uniform_jitter(self, ratio: f64) -> Self

Create a config with uniform jitter (±ratio).

pub fn with_full_jitter(self) -> Self

Create a config with full jitter (random between 0 and delay).

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.
