- /**
- * Returns a connectable observable sequence that shares a single subscription to the
- * underlying sequence containing only the last notification.
- *
- * 
- *
- * Similar to {@link publish}, but it waits until the source observable completes and stores
- * the last emitted value.
- * Similarly to {@link publishReplay} and {@link publishBehavior}, this keeps storing the last
- * value even if it has no more subscribers. If subsequent subscriptions happen, they will
- * immediately get that last stored value and complete.
- *
- * ## Example
- *
- * ```ts
- * import { ConnectableObservable, interval, publishLast, tap, take } from 'rxjs';
- *
- * const connectable = <ConnectableObservable<number>>interval(1000)
- * .pipe(
- * tap(x => console.log('side effect', x)),
- * take(3),
- * publishLast()
- * );
- *
- * connectable.subscribe({
- * next: x => console.log('Sub. A', x),
- * error: err => console.log('Sub. A Error', err),
- * complete: () => console.log('Sub. A Complete')
- * });
- *
- * connectable.subscribe({
- * next: x => console.log('Sub. B', x),
- * error: err => console.log('Sub. B Error', err),
- * complete: () => console.log('Sub. B Complete')
- * });
- *
- * connectable.connect();
- *
- * // Results:
- * // 'side effect 0' - after one second
- * // 'side effect 1' - after two seconds
- * // 'side effect 2' - after three seconds
- * // 'Sub. A 2' - immediately after 'side effect 2'
- * // 'Sub. B 2'
- * // 'Sub. A Complete'
- * // 'Sub. B Complete'
- * ```

- *
- * @return A function that returns an Observable that emits elements of a
- * sequence produced by multicasting the source sequence.
- * @deprecated Will be removed in v8. To create a connectable observable with an
- * {@link AsyncSubject} under the hood, use {@link connectable}.
- * `source.pipe(publishLast())` is equivalent to
- * `connectable(source, { connector: () => new AsyncSubject(), resetOnDisconnect: false })`.
- * If you're using {@link refCount} after `publishLast`, use the {@link share} operator instead.
- * `source.pipe(publishLast(), refCount())` is equivalent to
- * `source.pipe(share({ connector: () => new AsyncSubject(), resetOnError: false, resetOnComplete: false, resetOnRefCountZero: false }))`.
