        lease: LeaseId,
        id: TaskId,
        reason: AbortReason,

Expand description

Something the driver must do.

Variants§

Dispatch(Dispatch<P>)

Run an attempt on a free worker of its pool.

Abort

Stop the attempt (the engine already treats it as finished).

Fields

§lease: LeaseId

Lease of the attempt.

§id: TaskId

Task id.

§reason: AbortReason

Why it was aborted.

ScaleTo

Ask the pool’s scaler for desired workers; report back with set_capacity.

Fields

§pool: PoolId

Pool to scale.

§desired: u32

Requested worker count.

Status(StatusEvent)

A task changed status.

Persist(Box<Mutation<P>>)

Write this mutation to durable storage (only with CoreConfig::persist).

SpaceAvailable

Space freed after a SubmitError::Full; waiting submitters may retry.
