Struct RetryPolicy 

pub struct RetryPolicy { /* private fields */ }

Bounded exponential-backoff policy with full jitter.

Implementations

impl RetryPolicy

pub fn standard() -> Self

Creates a policy with production-oriented defaults.

pub fn new( max_attempts: u32, base_delay: Duration, max_delay: Duration, max_elapsed: Duration, ) -> Result<Self, S3Error>

Creates and validates a retry policy.

pub fn max_attempts(&self) -> u32

Returns the total number of allowed attempts, including the initial attempt.

pub fn base_delay(&self) -> Duration

Returns the initial backoff delay.

pub fn max_delay(&self) -> Duration

Returns the maximum delay between attempts.

pub fn max_elapsed(&self) -> Duration

Returns the maximum elapsed time in which another attempt may begin.

pub fn permits_retry( &self, classification: RetryClassification, attempts_completed: u32, elapsed: Duration, ) -> bool

Returns whether another attempt is allowed by classification and bounds.

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

Computes a full-jitter delay after attempts_completed attempts.

A server-provided Retry-After value is honored exactly when it fits within the remaining elapsed-time bound.

pub fn delay_for( &self, classification: RetryClassification, attempts_completed: u32, elapsed: Duration, retry_after: Option<Duration>, ) -> Option<Duration>

Computes a classification-aware full-jitter delay.

Standard AWS retry behavior uses a one-second backoff base for throttling and a shorter base for other transient failures.
