Struct RetryPolicy 

pub struct RetryPolicy {
    pub max_attempts: u32,
    pub backoff: BackoffStrategy,
    pub initial_delay: Duration,
    pub max_delay: Duration,
    pub jitter: bool,
    pub retryable_on: Vec<ErrorClass>,
}

Defines how a node retries on failure.

Fields

max_attempts: u32

Maximum number of attempts (including the first). Must be >= 1.

backoff: BackoffStrategy

Backoff strategy between attempts.

initial_delay: Duration

Initial delay before the first retry.

max_delay: Duration

Maximum delay cap (exponential backoff will not exceed this).

jitter: bool

Whether to add random jitter to delays (prevents thundering herd).

retryable_on: Vec<ErrorClass>

Which error classes are retryable. Empty = retry on any error.

Implementations

impl RetryPolicy

pub fn io_default() -> Self

A sensible default for I/O-bound tool calls.

pub fn llm_default() -> Self

A sensible default for LLM calls.

pub fn no_retry() -> Self

No retries — fail immediately on any error.

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

Compute the delay before the nth retry (0-indexed).
