initial_delay: Duration

Initial delay between retries

max_delay: Duration

Maximum delay between retries

backoff_multiplier: f64

Multiplier for exponential backoff

jitter: f64

retry_queue_pattern: String

Retry queue naming pattern

dead_letter_exchange: Option<String>

Dead letter exchange for failed messages

dead_letter_queue: Option<String>

Implementations

impl RetryPolicy

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

Calculate delay for a specific retry attempt

pub fn get_retry_queue_name(&self, original_queue: &str, attempt: u32) -> String

Generate retry queue name for a specific attempt

pub fn fast() -> Self

Create a fast retry policy (quick retries for transient errors)

pub fn fast_for_queue<S: Into<String>>(queue_name: S) -> Self

Create a fast retry policy with custom dead letter names based on queue

pub fn slow() -> Self

Create a slow retry policy (for operations that need more time)

pub fn slow_for_queue<S: Into<String>>(queue_name: S) -> Self

Create a slow retry policy with custom dead letter names based on queue

pub fn aggressive() -> Self

Create an aggressive retry policy (many attempts with exponential backoff)

pub fn conservative() -> Self

Create a conservative retry policy (few attempts, larger delays)

pub fn linear(delay: Duration, max_retries: u32) -> Self

Create a linear retry policy (fixed delay between retries)

pub fn no_retry() -> Self

Create a no-retry policy (fail immediately, no retries)

pub fn minutes_exponential() -> Self

Create a minutes-based exponential retry policy (1min, 2min, 4min, 8min, 16min)

pub fn minutes_exponential_for_queue<S: Into<String>>(queue_name: S) -> Self

Create a minutes-based exponential retry policy with custom dead letter names

pub fn builder() -> RetryPolicyBuilder

Create a custom retry policy with builder pattern
