  * Returns an Observable that will resubscribe to the source stream when the source stream completes, at most count times.
  *
  + * <span class="informal">Repeats all values emitted on the source. It's like {@link retry}, but for non error cases.</span>

  * ![](repeat.png)
  *
  + * Similar to {@link retry}, this operator repeats the stream of items emitted by the source for non error cases.
  + * Repeat can be useful for creating observables that are meant to have some repeated pattern or rhythm.
  + *
  + * Note: `repeat(0)` returns an empty observable and `repeat()` will repeat forever
  + *
  + * ## Example
  + * Repeat a message stream
  + * ```ts
  + * import { of } from 'rxjs';
  + * import { repeat, delay } from 'rxjs/operators';
  + *
  + * const source = of('Repeat message');
  + * const example = source.pipe(repeat(3));
  + * example.subscribe(x => console.log(x));
  + *
  + * // Results
  + * // Repeat message
  + * // Repeat message
  + * // Repeat message
  + * ```
  + *
  + * Repeat 3 values, 2 times
  + * ```ts
  + * import { interval } from 'rxjs';
  + * import { repeat, take } from 'rxjs/operators';
  + *
  + * const source = interval(1000);
  + * const example = source.pipe(take(3), repeat(2));
  + * example.subscribe(x => console.log(x));
  + *
  + * // Results every second
  + * // 0
  + * // 1
  + * // 2
  + * // 0
  + * // 1
  + * // 2
  + * ```
  + *
  + * @see {@link repeatWhen}
  + * @see {@link retry}
  + *
  * @param {number} [count] The number of times the source Observable items are repeated, a count of 0 will yield
  * an empty Observable.
  * @return {Observable} An Observable that will resubscribe to the source stream when the source stream completes
