#[non_exhaustive]
pub enum RetryAction { NoActionIndicated, RetryIndicated(RetryReason), RetryForbidden, }
Expand description

The result of running a ClassifyRetry on a InterceptorContext.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

NoActionIndicated

When a classifier can’t run or has no opinion, this action is returned.

For example, if a classifier requires a parsed response and response parsing failed, this action is returned. If all classifiers return this action, no retry should be attempted.

§

RetryIndicated(RetryReason)

When a classifier runs and thinks a response should be retried, this action is returned.

§

RetryForbidden

When a classifier runs and decides a response must not be retried, this action is returned.

This action stops retry classification immediately, skipping any following classifiers.
