Struct RetryPolicy 

pub struct RetryPolicy {
    pub max_retries: u32,
    pub backoff: BackoffStrategy,
}

Configurable retry policy for individual Axon transitions.

Fields

max_retries: u32

Maximum number of retry attempts (not counting the initial attempt).

backoff: BackoffStrategy

Backoff strategy between retries.

Implementations

impl RetryPolicy

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

Create a retry policy with fixed delay between attempts.

pub fn exponential( max_retries: u32, initial: Duration, multiplier: f64, max: Duration, ) -> Self

Create a retry policy with exponential backoff.

Arguments

• max_retries: Maximum number of retry attempts
• initial: Initial delay (e.g., 100ms)
• multiplier: Backoff multiplier (e.g., 2.0 for doubling)
• max: Maximum delay cap

pub fn exponential_default(max_retries: u32, initial_ms: u64) -> Self

Convenience: exponential backoff starting at initial_ms milliseconds, doubling each time, capped at 30 seconds.

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

Calculate the delay for the given attempt number (0-indexed).
