| * Branch out the source Observable values as a nested Observable starting from |
| * an emission from `openings` and ending when the output of `closingSelector` |
| * emits. |
| * |
| * <span class="informal">It's like {@link bufferToggle}, but emits a nested |
| * Observable instead of an array.</span> |
| * |
| *  |
| * |
| * Returns an Observable that emits windows of items it collects from the source |
| * Observable. The output Observable emits windows that contain those items |
| * emitted by the source Observable between the time when the `openings` |
| * Observable emits an item and when the Observable returned by |
| * `closingSelector` emits an item. |
| * |
| * ## Example |
| * Every other second, emit the click events from the next 500ms |
| * ```ts |
| * import { fromEvent, interval, EMPTY } from 'rxjs'; |
| * import { windowToggle, mergeAll } from 'rxjs/operators'; |
| * |
| * const clicks = fromEvent(document, 'click'); |
| * const openings = interval(1000); |
| * const result = clicks.pipe( |
| * windowToggle(openings, i => i % 2 ? interval(500) : EMPTY), |
| * mergeAll() |
| * ); |
| * result.subscribe(x => console.log(x)); |
| * ``` |

| * @param {Observable<O>} openings An observable of notifications to start new |
| * windows. |
| * @param {function(value: O): Observable} closingSelector A function that takes |
| * the value emitted by the `openings` observable and returns an Observable, |
| * which, when it emits (either `next` or `complete`), signals that the |
| * associated window should complete. |
| * @return {Observable<Observable<T>>} An observable of windows, which in turn |
| * are Observables. |
