Struct RetryPolicy 

pub struct RetryPolicy {
    pub max_retries: u32,
    pub initial_delay: Duration,
    pub backoff_factor: f64,
    pub max_retry_after: Duration,
    pub jitter: Jitter,
}

How failed provider calls are retried.

Fields

max_retries: u32

Maximum number of retries after the first attempt (default 2).

initial_delay: Duration

Delay before the first retry (default 2 s).

backoff_factor: f64

Multiplier applied to the delay after each retry (default 2.0).

max_retry_after: Duration

Largest Retry-After value that is honoured (default 60 s).

jitter: Jitter

Random jitter applied to the computed delay (default none).

Implementations

impl RetryPolicy

pub fn with_max_retries(max_retries: u32) -> Self

Creates the default policy with a different retry count.

pub fn none() -> Self

Disables retries.

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

Computes the delay before retry number retry (1-based), honouring Retry-After headers when they fall within max_retry_after.

Arithmetic overflow saturates at Duration::MAX. Provider calls reject negative or non-finite backoff factors before using this policy.

Trait Implementations
