Expand description

A task handed to an executor.

Fields§

§lease: LeaseId

Lease identifying this attempt; pass it back to complete and heartbeat.

§id: TaskId

Task id.

§pool: PoolId

Pool the task runs in.

§attempt: u32

Attempt number, starting at 1.

§payload: Arc<P>

Opaque task payload.

§kind: Arc<str>

Task kind (selects the handler).

§key: Option<Arc<str>>

Idempotency key, if any.

§timeout: Option<Duration>

Per-attempt timeout, if any.

§deadline: Option<Time>

Completion deadline, if any.

§tags: Tags

Task tags.

§group: Labels

Labels of the worker group chosen for this attempt (empty for the unlabeled group); a driver with several groups must run the attempt on a worker of this group.
