Struct RetryPolicy 

pub struct RetryPolicy {
    pub max_attempts: u32,
    pub initial_delay: Duration,
    pub max_delay: Duration,
    pub multiplier: f64,
    pub jitter: f64,
}

Typed retry policy shared across runtime layers.

Fields

max_attempts: u32

Maximum number of total attempts, including the initial call.

initial_delay: Duration

max_delay: Duration

multiplier: f64

jitter: f64

Implementations

impl RetryPolicy

pub fn new( max_attempts: u32, initial_delay: Duration, max_delay: Duration, multiplier: f64, ) -> Self

pub fn from_retries( max_retries: u32, initial_delay: Duration, max_delay: Duration, multiplier: f64, ) -> Self

pub fn simple(max_retries: u32, base_delay_ms: u64, max_delay_ms: u64) -> Self

Millisecond-based constructor for wire clients.

Uses a 2.0 multiplier and no jitter, so Self::delay_for_attempt reproduces the classic base_ms << attempt doubling curve capped at max_delay_ms.

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

pub fn decision_for_category( &self, category: ErrorCategory, attempt_index: u32, retry_after: Option<Duration>, ) -> RetryDecision

pub fn classify_anyhow(&self, error: &Error) -> RetryDecision

Classify an anyhow::Error for retry eligibility.

Attempt-agnostic: retryable reflects only the error category, not the remaining attempt budget. Wire clients that manage their own attempt counting use this; loops that want budget-aware decisions use Self::decision_for_category.

pub fn classify_status(&self, status: u16) -> RetryDecision

Classify an HTTP status code for retry eligibility.

Attempt-agnostic, like Self::classify_anyhow.

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 Copy for RetryPolicy

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.

impl Serialize for RetryPolicy

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
