enum WorkerStatus { // Not yet scheduled.
Pending = 0,
// This status means that the worker is active.
Running,
// Inner script called close() on the worker global scope. Setting this // status causes the worker to clear its queue of events but does not abort // the currently running script. WorkerRef objects are not going to be // notified because the behavior of APIs/Components should not change during // this status yet.
Closing,
// Either the user navigated away from the owning page or the owning page fell // out of bfcache. Setting this status causes the worker to abort immediately. // Since the page has gone away the worker may not post any messages.
Canceling,
// The application is shutting down. Setting this status causes the worker to // abort immediately.
Killing,
// The worker is effectively dead.
Dead
