Struct RetryPolicy 

pub struct RetryPolicy {
    pub max_retries: u32,
    pub base_delay: Duration,
    pub max_delay: Duration,
    pub jitter: bool,
}

Unified retry policy configuration

All external calls (LLM / MCP / A2A / Sandbox) should control retry behavior via this policy.

Fields

max_retries: u32

Maximum number of retries (0 = no retry, single attempt only)

base_delay: Duration

Initial wait duration (base for exponential backoff)

max_delay: Duration

Maximum wait duration cap

jitter: bool

Whether to add random jitter (prevents thundering herd with multiple clients retrying simultaneously)

Implementations

impl RetryPolicy

pub fn new(max_retries: u32, base_delay: Duration) -> RetryPolicy

Create a retry policy with a retry count and base backoff delay.

pub fn max_delay(self, delay: Duration) -> RetryPolicy

Set the maximum delay allowed after exponential backoff.

pub fn jitter(self, enabled: bool) -> RetryPolicy

Enable or disable randomized jitter for retry delays.

pub fn no_retry() -> RetryPolicy

No retry (single attempt only).

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

Calculate the wait duration for retry attempt attempt (0-indexed: attempt 1 = first retry).

Note: attempt=0 means the first execution (no delay), returns Duration::ZERO.

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<(), Error>

Formats the value using the given formatter.

impl Default for RetryPolicy

fn default() -> RetryPolicy

Returns the “default value” for a type.
