Struct RetryPolicy 

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

Exponential back-off retry configuration.

Fields

max_attempts: u32

Maximum number of total attempts (first attempt + retries).

initial_delay_ms: u64

Delay before the first retry, in milliseconds.

max_delay_ms: u64

Upper bound on the computed delay, in milliseconds.

backoff_multiplier: f64

Multiplicative factor applied to the delay after each attempt.

jitter_factor: f64

Fraction of the computed delay to use as random jitter in [0, 1]. 0.0 = no jitter, 1.0 = full ±100 % jitter.

Implementations

impl RetryPolicy

pub fn new() -> Self

Default policy: 3 attempts, 100 ms initial, 30 s cap, ×2 back-off, 10 % jitter.

pub fn no_retry() -> Self

No retries — fail immediately on the first error.

pub fn aggressive() -> Self

Aggressive policy: 5 attempts, 50 ms initial, 60 s cap, ×2 back-off, 10 % jitter.

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

Compute the delay before attempt attempt (0-indexed).

Formula: min(initial * multiplier^attempt, max) * (1 ± jitter)

Jitter is deterministic: it is derived from the attempt number using an LCG so that tests are reproducible without a PRNG dependency.

pub fn is_retryable(error: &CloudError) -> bool

Returns true if the error is considered transient and worth retrying.

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 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.
