Struct RetryPolicy 

pub struct RetryPolicy {
    pub max_attempts: u32,
    pub initial_delay_ms: u64,
    pub backoff_multiplier: f64,
    pub max_delay_ms: u64,
    pub on_exhausted: ExhaustedPolicy,
}

Configures retry behavior for components that support it.

On each failure the component logs a warning, waits for the computed delay, then tries again. When all attempts are exhausted, on_exhausted determines what happens next (see ExhaustedPolicy).

The delay before the Nth retry (0-indexed) is:

delay = min(initial_delay_ms * backoff_multiplier ^ N, max_delay_ms)

Set max_attempts = 1 to disable retries (first failure immediately triggers on_exhausted).

Fields

max_attempts: u32

Total number of attempts, including the first. Must be ≥ 1.

initial_delay_ms: u64

Delay before the second attempt, in milliseconds.

backoff_multiplier: f64

Multiplier applied to the delay after each failed attempt. 1.0 = constant delay; 2.0 = exponential doubling.

max_delay_ms: u64

Upper bound on any single inter-attempt delay, in milliseconds.

on_exhausted: ExhaustedPolicy

What to do after all attempts are exhausted.

Implementations

impl RetryPolicy

pub fn delay_for(&self, retry: u32) -> Duration

Delay for the Nth retry (0-indexed: 0 = delay before 2nd attempt).

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

Formats the value using the given formatter.

impl Default for RetryPolicy

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RetryPolicy

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RetryPolicy

fn eq(&self, other: &RetryPolicy) -> 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.
