Enum RetryClass 

pub enum RetryClass {
    Never,
    IdempotencyKeyRequired,
    AfterMetadataRefresh,
    AfterBackoff,
    RetryTransaction,
}

The retry discipline for an ErrorCategory (spec section 11.7).

Variants

Never

Never retried automatically: the same request would re-fail (or the failure is caller intent), and only changing the request, the principal, or a version changes the outcome.

IdempotencyKeyRequired

Never blindly retried: the outcome is ambiguous, so a replay is only permitted with a durable idempotency key or an unambiguous not-proposed status (spec section 11.7).

AfterMetadataRefresh

Retryable after refreshing routing and/or schema metadata (leader hint, endpoint list, tablet map, schema version).

AfterBackoff

Retryable after a backoff delay once the transient condition (availability, quorum, resource pressure) clears.

RetryTransaction

Retryable by restarting the whole transaction from the beginning with a fresh snapshot.
