+/**
+ * An Observable that emits no items to the Observer and never completes.
+ *
+ * ![](never.png)
+ *
+ * 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}
+ */
