PerWorkflowSubscription

Struct PerWorkflowSubscription 

Source
pub struct PerWorkflowSubscription {
    pub namespace: String,
    pub workflow_id: Option<ProtoWorkflowId>,
    pub resume_from_seq: Option<u64>,
}
Expand description

Subscribe to events for one workflow.

Fields§

§namespace: String

Caller namespace used for adapter-boundary authorisation.

§workflow_id: Option<ProtoWorkflowId>

Workflow whose events are requested.

§resume_from_seq: Option<u64>

First per-workflow sequence number the caller wants — not the last seq already seen. When present, the server replays recorded history events with seq >= resume_from_seq in order, then splices into the live stream with no gaps and no duplicates. Sequence numbers start at 1; 0 is rejected as invalid_input. Absent = live tail only (current behaviour). resume_from_seq = 1 replays the full history.

Only per-workflow subscriptions carry a resume cursor: per-workflow seq is the only ordering that exists, so FilteredSubscription and FirehoseSubscription are live-only by design.

RESERVED compaction signal (documentation-only, no code yet): a cursor older than the earliest retained event yields not_found with error_type "HistoryCompacted"; callers restart with a fresh subscription.
