Struct RetryPolicy 

pub struct RetryPolicy {
    pub max_attempts: u32,
    pub initial_delay: Duration,
    pub max_delay: Duration,
    pub backoff_multiplier: f64,
    pub jitter_factor: f64,
    pub max_total_duration: Option<Duration>,
}

Policy for retrying failed operations with exponential backoff

Fields

max_attempts: u32

Maximum number of retry attempts (0 = no retries)

initial_delay: Duration

Initial delay before first retry

max_delay: Duration

Maximum delay between retries

backoff_multiplier: f64

Multiplier for exponential backoff (typically 2.0)

jitter_factor: f64

Add random jitter to prevent thundering herd (0.0 - 1.0) 0.0 = no jitter, 1.0 = full jitter (delay * random(0-1))

max_total_duration: Option<Duration>

Maximum total duration for all retries

Implementations

impl RetryPolicy

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

Create a new retry policy with custom settings

pub fn no_retry() -> Self

Disable retries

pub fn aggressive() -> Self

Aggressive retry for critical operations

pub fn conservative() -> Self

Conservative retry for expensive operations

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

Calculate delay for a given attempt number (0-indexed)

pub async fn execute<F, Fut, T, E>( &self, operation_name: &str, operation: F, ) -> Result<T, RuntimeError>

where F: FnMut() -> Fut, Fut: Future<Output = Result<T, E>>, E: Into<RuntimeError> + Clone,

Execute an async operation with retry logic

Example

use agent_runtime::retry::RetryPolicy;
use agent_runtime::{RuntimeError, LlmError};

let policy = RetryPolicy::default();
let result = policy.execute(
    "fetch_data",
    || async {
        // Your operation here - returns Result<T, impl Into<RuntimeError>>
        Ok::<String, LlmError>("success".to_string())
    }
).await?;

Trait Implementations

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RetryPolicy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Default for RetryPolicy

fn default() -> Self

Returns the “default value” for a type.
