Struct RetryPolicy 

pub struct RetryPolicy {
    pub max_attempts: u32,
    pub initial_backoff: Duration,
    pub max_backoff: Duration,
    pub multiplier: f64,
    pub jitter: f64,
    pub retry_statuses: Vec<u16>,
    pub honor_retry_after: bool,
    pub max_retry_after: Duration,
}

Retry/backoff policy. max_attempts counts total tries (1 = no retry).

Fields

max_attempts: u32

initial_backoff: Duration

max_backoff: Duration

multiplier: f64

jitter: f64

Fraction (0.0..=1.0) of each delay randomly shaved off; 0 = deterministic.

retry_statuses: Vec<u16>

honor_retry_after: bool

max_retry_after: Duration

Upper bound applied to a server-supplied Retry-After.

Implementations

impl RetryPolicy

pub fn none() -> Self

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

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

Delay before retry number retry (1 = after the first failure).

pub fn delay(&self, retry: u32, retry_after: Option<Duration>) -> Duration

Delay for a given failure: the larger of backoff and a (capped) Retry-After.
