It - * might be for example a function that you passed to Observable's constructor, but most of the time it is - * a library implementation, which defines what will be emitted by an Observable, and when it be will emitted. This means - * that calling `subscribe` is actually the moment when Observable starts its work, not when it is created, as it is often - * the thought. - * - * Apart from starting the execution of an Observable, this method allows you to listen for values - * that an Observable emits, as well as for when it completes or errors. You can achieve this in two - * of the following ways. - * - * The first way is creating an object that implements {@link Observer} interface. It should have methods - * defined by that interface, but note that it should be just a regular JavaScript object, which you can create - * yourself in any way you want (ES6 class, classic function constructor, object literal etc.). In particular, do - * not attempt to use any RxJS implementation details to create Observers - you don't need them. Remember also - * that your object does not have to implement all methods. If you find yourself creating a method that doesn't - * do anything, you can simply omit it. Note however, if the `error` method is not provided and an error happens, - * it will be thrown asynchronously. Errors thrown asynchronously cannot be caught using `try`/`catch`. Instead, - * use the {@link onUnhandledError} configuration option or use a runtime handler (like `window.onerror` or - * `process.on('error)`) to be notified of unhandled errors. Because of this, it's recommended that you provide - * an `error` method to avoid missing thrown errors. - * - * The second way is to give up on Observer object altogether and simply provide callback functions in place of its methods. - * This means you can provide three functions as arguments to `subscribe`, where the first function is equivalent - * of a `next` method, the second of an `error` method and the third of a `complete` method. Just as in case of an Observer, - * if you do not need to listen for something, you can omit a function by passing `undefined` or `null`, - * since `subscribe` recognizes these functions by where they were placed in function call. When it comes - * to the `error` function, as with an Observer, if not provided, errors emitted by an Observable will be thrown asynchronously. - * - * You can, however, subscribe with no parameters at all. This may be the case where you're not interested in terminal events - * and you also handled emissions internally by using operators (e.g. using `tap`). - * - * Whichever style of calling `subscribe` you use, in both cases it returns a Subscription object. - * This object allows you to call `unsubscribe` on it, which in turn will stop the work that an Observable does and will clean - * up all resources that an Observable used. Note that cancelling a subscription will not call `complete` callback - * provided to `subscribe` function, which is reserved for a regular completion signal that comes from an Observable. - * - * Remember that callbacks provided to `subscribe` are not guaranteed to be called asynchronously. - * It is an Observable itself that decides when these functions will be called. For example {@link of} - * by default emits all its values synchronously. Always check documentation for how given Observable - * will behave when subscribed and if its default behavior can be modified with a `scheduler`. - * - * #### Examples - * - * Subscribe with an {@link guide/observer Observer} - * - * ```ts - * import { of } from 'rxjs'; - * - * const sumObserver = { - * sum: 0, - * next(value) { - * console.log('Adding: ' + value); - * this.sum = this.sum + value; - * }, - * error() { - * // We actually could just remove this method, - * // since we do not really care about errors right now. - * }, - * complete() { - * console.log('Sum equals: ' + this.sum); - * } - * }; - * - * of(1, 2, 3) // Synchronously emits 1, 2, 3 and then completes. - * .subscribe(sumObserver); - * - * // Logs: - * // 'Adding: 1' - * // 'Adding: 2' - * // 'Adding: 3' - * // 'Sum equals: 6' - * ``` - * - * Subscribe with functions ({@link deprecations/subscribe-arguments deprecated}) - * - * ```ts - * import { of } from 'rxjs' - * - * let sum = 0; - * - * of(1, 2, 3).subscribe( - * value => { - * console.log('Adding: ' + value); - * sum = sum + value; - * }, - * undefined, - * () => console.log('Sum equals: ' + sum) - * ); - * - * // Logs: - * // 'Adding: 1' - * // 'Adding: 2' - * // 'Adding: 3' - * // 'Sum equals: 6' - * ``` - * - * Cancel a subscription - * - * ```ts - * import { interval } from 'rxjs'; - * - * const subscription = interval(1000).subscribe({ - * next(num) { - * console.log(num) - * }, - * complete() { - * // Will not be called, even when cancelling subscription. - * console.log('completed!'); - * } - * }); - * - * setTimeout(() => { - * subscription.unsubscribe(); - * console.log('unsubscribed!'); - * }, 2500); - * - * // Logs: - * // 0 after 1s - * // 1 after 2s - * // 'unsubscribed!' after 2.5s - * ``` - * - * @param observerOrNext Either an {@link Observer} with some or all callback methods, - * or the `next` handler that is called for each value emitted from the subscribed Observable. - * @param error A handler for a terminal event resulting from an error.

Because of This, `JSON.stringify` will have to be called on a value by hand, - * before calling `next` with a result.

On the other hand, since calling `complete` triggers - * an attempt to close socket connection. If that connection is closed without any errors, stream will - * complete, thus notifying all subscribers. And since calling `error` closes - * socket connection as well, just with a different status code for the server, if closing itself proceeds - * without errors, subscribed Observable will not error, as one might expect, but complete as usual. In both cases - * (calling `complete` or `error`), if process of closing socket connection results in some errors, *then* stream - * will error. - * - * **Multiplexing** - * - * `WebSocketSubject` has an additional operator, not found in other Subjects. It is called `multiplex` and it is - * used to simulate opening several socket connections, while in reality maintaining only one. - * For example, an application has both chat panel and real-time notifications about sport news. Since these are two distinct functions, - * it would make sense to have two separate connections for each. Perhaps there could even be two separate services with WebSocket - * endpoints, running on separate machines with only GUI combining them together. Having a socket connection - * for each functionality could become too resource expensive. It is a common pattern to have single - * WebSocket endpoint that acts as a gateway for the other services (in this case chat and sport news services). - * Even though there is a single connection in a client app, having the ability to manipulate streams as if it - * were two separate sockets is desirable. This eliminates manually registering and unregistering in a gateway for - * given service and filter out messages of interest. This is exactly what `multiplex` method is for. - * - * Method accepts three parameters. First two are functions returning subscription and unsubscription messages - * respectively. These are messages that will be sent to the server, whenever consumer of resulting Observable - * subscribes and unsubscribes. Server can use them to verify that some kind of messages should start or stop - * being forwarded to the client. In case of the above example application, after getting subscription message with proper identifier, - * gateway server can decide that it should connect to real sport news service and start forwarding messages from it. - * Note that both messages will be sent as returned by the functions, they are by default serialized using JSON.stringify, just - * as messages pushed via `next`. Also bear in mind that these messages will be sent on *every* subscription and - * unsubscription. This is potentially dangerous, because one consumer of an Observable may unsubscribe and the server - * might stop sending messages, since it got unsubscription message. This needs to be handled - * on the server or using {@link publish} on a Observable returned from 'multiplex'. - * - * Last argument to `multiplex` is a `messageFilter` function which should return a boolean. It is used to filter out messages - * sent by the server to only those that belong to simulated WebSocket stream. For example, server might mark these - * messages with some kind of string identifier on a message object and `messageFilter` would return `true` - * if there is such identifier on an object emitted by the socket. Messages which returns `false` in `messageFilter` are simply skipped, - * and are not passed down the stream. - * - * Return value of `multiplex` is an Observable with messages incoming from emulated socket connection. Note that this - * is not a `WebSocketSubject`, so calling `next` or `multiplex` again will fail. For pushing values to the - * server, use root `WebSocketSubject`. - * - * ## Examples - * - * Listening for messages from the server - * - * ```ts - * import { webSocket } from 'rxjs/webSocket'; - * - * const subject = webSocket('ws://localhost:8081'); - * - * subject.subscribe({ - * next: msg => console.log('message received: ' + msg), // Called whenever there is a message from the server. - * error: err => console.log(err), // Called if at any point WebSocket API signals some kind of error. - * complete: () => console.log('complete') // Called when connection is closed (for whatever reason). - * }); - * ``` - * - * Pushing messages to the server - * - * ```ts - * import { webSocket } from 'rxjs/webSocket'; - * - * const subject = webSocket('ws://localhost:8081'); - * - * subject.subscribe(); - * // Note that at least one consumer has to subscribe to the created subject - otherwise "nexted" values will be just buffered and not sent, - * // since no connection was established! - * - * subject.next({ message: 'some message' }); - * // This will send a message to the server once a connection is made.

When - * `fromEvent` is used with event target of that type, you can provide this values - * as third parameter as well. - * - * **Node.js EventEmitter** - * - * An object with `addListener` and `removeListener` methods. - * - * **JQuery-style event target** - * - * An object with `on` and `off` methods - * - * **DOM NodeList** - * - * List of DOM Nodes, returned for example by `document.querySelectorAll` or `Node.childNodes`. - * - * Although this collection is not event target in itself, `fromEvent` will iterate over all Nodes - * it contains and install event handler function in every of them. When returned Observable - * is unsubscribed, function will be removed from all Nodes. - * - * **DOM HtmlCollection** - * - * Just as in case of NodeList it is a collection of DOM nodes.

The first argument of `generate` is a beginning value. The second argument - * is a function that accepts this value and tests if some condition still holds. If it does, - * then the loop continues, if not, it stops. The third value is a function which takes the - * previously defined value and modifies it in some way on each iteration. Note how these three parameters - * are direct equivalents of three expressions in a traditional for loop: the first expression - * initializes some state (for example, a numeric index), the second tests if the loop can perform the next - * iteration (for example, if the index is lower than 10) and the third states how the defined value - * will be modified on every step (for example, the index will be incremented by one). - * - * Return value of a `generate` operator is an Observable that on each loop iteration - * emits a value. First of all, the condition function is ran. If it returns true, then the Observable - * emits the currently stored value (initial value at the first iteration) and finally updates - * that value with iterate function. If at some point the condition returns false, then the Observable - * completes at that moment. - * - * Optionally you can pass a fourth parameter to `generate` - a result selector function which allows you - * to immediately map the value that would normally be emitted by an Observable. - * - * If you find three anonymous functions in `generate` call hard to read, you can provide - * a single object to the operator instead where the object has the properties: `initialState`, - * `condition`, `iterate` and `resultSelector`, which should have respective values that you - * would normally pass to `generate`. `resultSelector` is still optional, but that form - * of calling `generate` allows you to omit `condition` as well. If you omit it, that means - * condition always holds, or in other words the resulting Observable will never complete. - * - * Both forms of `generate` can optionally accept a scheduler. In case of a multi-parameter call, - * scheduler simply comes as a last argument (no matter if there is a `resultSelector` - * function or not). In case of a single-parameter call, you can provide it as a - * `scheduler` property on the object passed to the operator. In both cases, a scheduler decides when - * the next iteration of the loop will happen and therefore when the next value will be emitted - * by the Observable. For example, to ensure that each value is pushed to the Observer - * on a separate task in the event loop, you could use the `async` scheduler.

The most common way to handle - * the error would be with {@link catchError}, although you could use {@link tap} or just the error handler in your `subscribe` call - * directly, if your error handling is only a side effect (such as notifying the user, or logging). - * - * In this case, you would check the error for `instanceof TimeoutError` to validate that the error was indeed from `timeout`, and - * not from some other source. If it's not from `timeout`, you should probably rethrow it if you're in a `catchError`. - * - * ## Examples - * - * Emit a {@link TimeoutError} if the first value, and _only_ the first value, does not arrive within 5 seconds - * - * ```ts - * import { interval, timeout } from 'rxjs'; - * - * // A random interval that lasts between 0 and 10 seconds per tick - * const source$ = interval(Math.round(Math.random() * 10_000)); - * - * source$.pipe( - * timeout({ first: 5_000 }) - * ) - * .subscribe({ - * next: console.log, - * error: console.error - * }); - * ``` - * - * Emit a {@link TimeoutError} if the source waits longer than 5 seconds between any two values or the first value - * and subscription. - * - * ```ts - * import { timer, timeout, expand } from 'rxjs'; - * - * const getRandomTime = () => Math.round(Math.random() * 10_000); - * - * // An observable that waits a random amount of time between each delivered value - * const source$ = timer(getRandomTime()) - * .pipe(expand(() => timer(getRandomTime()))); - * - * source$ - * .pipe(timeout({ each: 5_000 })) - * .subscribe({ - * next: console.log, - * error: console.error - * }); - * ``` - * - * Emit a {@link TimeoutError} if the source does not emit before 7 seconds, _or_ if the source waits longer than - * 5 seconds between any two values after the first. - * - * ```ts - * import { timer, timeout, expand } from 'rxjs'; - * - * const getRandomTime = () => Math.round(Math.random() * 10_000); - * - * // An observable that waits a random amount of time between each delivered value - * const source$ = timer(getRandomTime()) - * .pipe(expand(() => timer(getRandomTime()))); - * - * source$ - * .pipe(timeout({ first: 7_000, each: 5_000 })) - * .subscribe({ - * next: console.log, - * error: console.error - * }); - * ``` - */ -export function timeout<T, M = unknown>(config: Omit<TimeoutConfig<T, any, M>, 'with'>): OperatorFunction<T, T>; - -/** - * Returns an observable that will error if the source does not push its first value before the specified time passed as a `Date`. - * This is functionally the same as `timeout({ first: someDate })`. - * - * <span class="informal">Errors if the first value doesn't show up before the given date and time</span> - * - *  - * - * @param first The date to at which the resulting observable will timeout if the source observable - * does not emit at least one value. - * @param scheduler The scheduler to use.
