- * An Observable that emits no items to the Observer and never completes.
- *
- * 
- *
- * A simple Observable that emits neither values nor errors nor the completion
- * notification. It can be used for testing purposes or for composing with other
- * Observables. Please note that by never emitting a complete notification, this
- * Observable keeps the subscription from being disposed automatically.
- * Subscriptions need to be manually disposed.
- *
- * ## Example
- *
- * Emit the number 7, then never emit anything else (not even complete)
- *
- * ```ts
- * import { NEVER, startWith } from 'rxjs';
- *
- * const info = () => console.log('Will not be called');
- *
- * const result = NEVER.pipe(startWith(7));
- * result.subscribe({
- * next: x => console.log(x),
- * error: info,
- * complete: info
- * });
- * ```
- *
- * @see {@link Observable}
- * @see {@link EMPTY}
- * @see {@link of}
- * @see {@link throwError}
