| /** |
| * Creates cold [flowable][Flowable] that will run a given [block] in a coroutine. |
| * Every time the returned flowable is subscribed, it starts a new coroutine. |
| * |
| * Coroutine emits ([ObservableEmitter.onNext]) values with `send`, completes ([ObservableEmitter.onComplete]) |
| * when the coroutine completes or channel is explicitly closed and emits error ([ObservableEmitter.onError]) |
| * if coroutine throws an exception or closes channel with a cause. |
| * Unsubscribing cancels running coroutine. |
| * |
| * Invocations of `send` are suspended appropriately when subscribers apply back-pressure and to ensure that |
| * `onNext` is not invoked concurrently. |
| * |
| * Coroutine context can be specified with [context] argument. |
| * If the context does not have any dispatcher nor any other [ContinuationInterceptor], then [Dispatchers.Default] is used. |
| * Method throws [IllegalArgumentException] if provided [context] contains a [Job] instance. |
| * |
| * **Note: This is an experimental api.** Behaviour of publishers that work as children in a parent scope with respect |
