TaskPoolError

Failures scheduling or closing a reusable worker pool.

public enum TaskPoolError

InvalidSize

The requested worker count was zero or negative.

InvalidSize

Closed

The pool was closed and no longer accepts work.

Closed

Cancelled

Cancellation was requested; any submitted work has settled before this is returned.

Cancelled

WorkerCrashed

The worker running the job stopped before replying: the job trapped, the worker thread exited, a message could not be delivered, or the worker did not start within 10 seconds. The job's result is lost, and objects it held when it stopped stay allocated. The pool replaces the worker, so later dispatches still run. Only the JavaScript hosts report this; on native, a trapping job ends the process.

WorkerCrashed

code

Returns EINVAL, ECLOSED, ECANCELED, or EWORKER for the variant.

public fun code(): string
