Enum HandlerOutcome 

#[non_exhaustive]
pub enum HandlerOutcome {
    Ack,
    Retry,
    DeadLetter {
        reason: &'static str,
        detail: String,
    },
}

What a handler answers. The worker turns it into a super::delivery::Delivery with super::delivery::decide.

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.

Ack

Done: never deliver it again.

Retry

Failed for now: deliver it again later, until the cap.

DeadLetter

Never deliver it again, and keep a dead letter saying why.

Fields

reason: &'static str

One of the REASON_* codes.
