Struct ActivityStreamKey 

pub struct ActivityStreamKey {
    pub workflow_id: WorkflowId,
    pub activity_id: ActivityId,
    pub attempt: u32,
}

The durable key of one observability stream: a (workflow, activity, attempt) triple. Every ActivityRecord for one running agent attempt shares this key and is ordered by store_seq within it.

Fields

workflow_id: WorkflowId

The workflow the activity belongs to.

activity_id: ActivityId

The activity within the workflow.

attempt: u32

The attempt number — the third key axis (NOI-0). Two attempts of one activity are DISTINCT streams; a within-attempt failover shares one stream (so a dying + adopting worker’s events dedupe), while a retry is a new attempt and therefore a new stream.

Implementations

impl ActivityStreamKey

pub const fn new( workflow_id: WorkflowId, activity_id: ActivityId, attempt: u32, ) -> Self

Build a stream key from its three components.

pub fn of(event: &ActivityEvent) -> Self

The stream key an ActivityEvent belongs to.
