Enum DeadLetterCause 

#[non_exhaustive]
pub enum DeadLetterCause {
    Unspecified,
    AttemptsExhausted,
    Rejected,
    LeaseExpired,
    Admin,
}

Why a job was moved to the server’s dead-letter store.

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.

Unspecified

The cause was unset — an unknown or future variant.

AttemptsExhausted

The job exhausted its max attempts across nacks and redeliveries.

Rejected

A worker nacked with RetryDirective::DeadLetter, skipping its remaining attempts.

LeaseExpired

The lease expired while the job was on its final attempt.

Admin

An operator dead-lettered the job through the admin API.
