Struct ActivityTask 

pub struct ActivityTask {
    pub workflow_id: Option<WorkflowId>,
    pub activity_id: Option<ActivityId>,
    pub activity_type: String,
    pub input: Option<Payload>,
    pub attempt: u32,
    pub labels: HashMap<String, String>,
    pub run_id: Option<RunId>,
    pub completion_token: String,
    pub idempotency_key: String,
}

Activity invocation pushed by the server to a registered worker.

Fields

workflow_id: Option<WorkflowId>

activity_id: Option<ActivityId>

activity_type: String

input: Option<Payload>

attempt: u32

One-based delivery attempt stamped by the dispatching engine seam. Zero is malformed: consumers MUST reject a task whose attempt is 0 (proto3 default = the producer failed to stamp it).

labels: HashMap<String, String>

Human-meaningful display labels the workflow attached to the activity (for example brief=IP-001, repo=ablative-io/yggdrasil). Display metadata only: the engine never interprets them and they never affect routing or replay. Carried purely so worker logs and the dashboard can show what a dispatch is working on. Absent (empty map) when the workflow set none.

run_id: Option<RunId>

Concrete run that owns this task. New servers MUST stamp it; a missing run cannot produce a run-scoped idempotency key and is refused before dispatch.

completion_token: String

Opaque proof of this execution generation. Workers MUST echo it verbatim on ActivityResult and MUST NOT infer or synthesize it. Empty means the server is from an incompatible pre-fencing registration era.

idempotency_key: String

Stable external-effect key derived from workflow id + run id + activity site. It is intentionally independent of attempt and execution generation.
