- /**
- *
- * Queue Scheduler
- *
- * <span class="informal">Put every next task on a queue, instead of executing it immediately</span>
- *
- * `queue` scheduler, when used with delay, behaves the same as {@link asyncScheduler} scheduler.
- *
- * When used without delay, it schedules given task synchronously - executes it right when
- * it is scheduled. However when called recursively, that is when inside the scheduled task,
- * another task is scheduled with queue scheduler, instead of executing immediately as well,
- * that task will be put on a queue and wait for current one to finish.
- *
- * This means that when you execute task with `queue` scheduler, you are sure it will end
- * before any other task scheduled with that scheduler will start.
- *
- * ## Examples
- * Schedule recursively first, then do something
- * ```javascript
- * Rx.Scheduler.queue.schedule(() => {
- * Rx.Scheduler.queue.schedule(() => console.log('second')); // will not happen now, but will be put on a queue
- *
- * console.log('first');
- * });
- *
- * // Logs:
- * // "first"
- * // "second"
- * ```
- *
- * Reschedule itself recursively
- * ```javascript
- * Rx.Scheduler.queue.schedule(function(state) {
- * if (state !== 0) {
- * console.log('before', state);
- * this.schedule(state - 1); // `this` references currently executing Action,
- * // which we reschedule with new state
- * console.log('after', state);
- * }
- * }, 0, 3);
- *
- * // In scheduler that runs recursively, you would expect:
- * // "before", 3
- * // "before", 2
- * // "before", 1
- * // "after", 1
- * // "after", 2
- * // "after", 3
- *
- * // But with queue it logs:
- * // "before", 3
- * // "after", 3
- * // "before", 2
- * // "after", 2
- * // "before", 1
- * // "after", 1
- * ```
- *
- * @static true
- * @name queue
- * @owner Scheduler
