Enum RetrySafety 

#[non_exhaustive]
pub enum RetrySafety {
    Safe,
    RequiresIdempotency,
    UnsafeAfterVisibleOutput,
    UnsafeAfterSideEffect,
    Unknown,
}

Whether retrying an operation is safe.

Variants (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.

Safe

The same operation can be retried safely.

RequiresIdempotency

Retry is safe only when the external system honors an idempotency key.

UnsafeAfterVisibleOutput

Visible output has been emitted, so retry may duplicate output.

UnsafeAfterSideEffect

An external side effect may already have occurred.

Unknown

Safety cannot be determined.
