Enum RetryOn 

pub enum RetryOn {
    Default,
    Predicate(Arc<dyn Fn(&Error) -> bool + Send + Sync>),
}

Which errors a RetryPolicy considers retryable.

Variants

Default

The built-in default predicate (see RetryPolicy docs for the exact rule): retries HTTP 408/429/5xx (Error::ServiceStatus) and transport-ish Error::Service failures (timeouts / connection errors). Never retries Error::ServiceInvalidAuth, Error::ServiceInvalidRequest, or Error::ServiceContentFilter — authentication/authorization failures, malformed requests, and content-filter refusals are non-transient, so retrying would just repeat the same rejection.

Predicate(Arc<dyn Fn(&Error) -> bool + Send + Sync>)

A fully custom predicate deciding, per error, whether to retry.
