Struct DefaultRetryStrategy 

pub struct DefaultRetryStrategy {
    pub max_attempts: u32,
    pub base_delay: Duration,
    pub max_delay: Duration,
    pub multiplier: f64,
    pub jitter: bool,
}

Exponential back-off retry strategy with optional jitter.

Only transient errors (AgentError::ModelThrottled and AgentError::NetworkError) are retried. All other error variants are considered non-retryable and cause an immediate exit.

Defaults

Field	Default
max_attempts	3
base_delay	1 second
max_delay	60 seconds
multiplier	2.0
jitter	true

Fields

max_attempts: u32

Maximum number of attempts (including the first). The strategy returns false from should_retry once attempt >= max_attempts.

base_delay: Duration

Base delay before the first retry (attempt 1).

max_delay: Duration

Upper bound on the computed delay — the delay is capped at this value regardless of the exponential growth.

multiplier: f64

Multiplicative factor applied per attempt.

jitter: bool

When true, the computed delay is multiplied by a random factor in [0.5, 1.5) to spread out retries across concurrent callers.

Implementations

impl DefaultRetryStrategy

pub const fn with_max_attempts(self, n: u32) -> Self

Set the maximum number of attempts.

pub const fn with_base_delay(self, d: Duration) -> Self

Set the base delay before the first retry.

pub const fn with_max_delay(self, d: Duration) -> Self

Set the maximum delay cap.

pub const fn with_multiplier(self, m: f64) -> Self

Set the exponential multiplier.

pub const fn with_jitter(self, j: bool) -> Self

Enable or disable jitter.

Trait Implementations

impl Clone for DefaultRetryStrategy

fn clone(&self) -> DefaultRetryStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DefaultRetryStrategy

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

Formats the value using the given formatter.

impl Default for DefaultRetryStrategy

fn default() -> Self

Returns the “default value” for a type.

impl From<&DefaultRetryStrategy> for RetryConfig

fn from(s: &DefaultRetryStrategy) -> Self

Converts to this type from the input type.

impl RetryStrategy for DefaultRetryStrategy

fn should_retry(&self, error: &AgentError, attempt: u32) -> bool

Returns true if error on the given attempt number should be retried. Attempt numbering starts at 1.

fn as_any(&self) -> &dyn Any

Downcast helper for type-safe access to concrete strategy types.

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

Returns the duration to wait before attempt number attempt. Attempt numbering starts at 1.
