常见的想当然

retry_unless_exception_type retries functions that raise unexpected exceptions while allowing successful returns to exit immediately without retrying.

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• retry_unless_exception_type treats successful return values as retryable states, retrying until stop exhaustion and raising RetryError with a successful last_attempt Future.
• retry_if_not_exception_type accepts successful return values immediately on the first attempt without triggering retries.
• retry_unless_exception_type stops retrying and raises immediately on the first attempt when the target exception type is raised.
• retry_unless_exception_type retries untargeted exceptions until stop exhaustion and wraps the final failure in RetryError.
