Struct ToolRetryPolicy 

pub struct ToolRetryPolicy {
    pub max_retries: usize,
    pub backoff: BackoffStrategy,
    pub retryable_patterns: Vec<String>,
}

Policy controlling when and how tool execution is retried on failure.

Fields

max_retries: usize

Maximum number of retry attempts (0 = no retries).

backoff: BackoffStrategy

Backoff strategy between attempts.

retryable_patterns: Vec<String>

If set, only errors whose message contains one of these substrings are retried.

Implementations

impl ToolRetryPolicy

pub fn exponential(max_retries: usize) -> Self

Creates a policy with exponential backoff (100ms base, 10s max).

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

Creates a policy with fixed delay between retries.

pub fn retryable_on(self, patterns: Vec<String>) -> Self

Only retry if the error message contains one of these substrings.

pub fn is_retryable(&self, error_msg: &str) -> bool

Returns true if the given error message is eligible for retry.
