Enum RedriveRefused 

pub enum RedriveRefused {
    Row(RedriveRefusal),
    WorkflowTerminal {
        workflow_id: WorkflowId,
        status: WorkflowStatus,
    },
    HistoryRecordsOutcome {
        workflow_id: WorkflowId,
        activity_id: ActivityId,
        ordinal: u64,
    },
    Store(StoreError),
}

Why a redrive did not happen, or could not be attempted.

Every variant is an explicit, typed refusal: a redrive request never resolves to a silent no-op, so an operator is never told “done” about work that was not re-queued.

Variants

Row(RedriveRefusal)

The store refused the transition (absent row, not a dead letter, or already judged).

WorkflowTerminal

The owning workflow already reached a hard terminal, so its rows must be settled, never re-armed — re-dispatching one would serve a zombie round for a dead workflow.

Fields

workflow_id: WorkflowId

The workflow that owns the dead letter.

status: WorkflowStatus

The status projected from its recorded history.

HistoryRecordsOutcome

The workflow’s recorded history already carries a terminal outcome for this activity, so judgment has passed even if the row’s judgment marker says otherwise (the crash window between delivering a failure and recording that it was delivered).

Fields

workflow_id: WorkflowId

The workflow that owns the dead letter.

activity_id: ActivityId

The activity the row dispatches.

ordinal: u64

The row’s fan-out ordinal.

Store(StoreError)

The store or history read failed; nothing was redriven.
