     *
     * @remarks
     * **NOTE:** If an abort signal aborts an operation while the driver is writing to the underlying
     * socket or reading the response from the server, the socket will be closed.
     * If signals are aborted at a high rate during socket read/writes this can lead to a high rate of connection reestablishment.
     *
     * We plan to mitigate this in a future release, please follow NODE-6062 (`timeoutMS` expiration suffers the same limitation).
     *
     * AbortSignals are likely a best fit for human interactive interruption (ex. ctrl-C) where the frequency
     * of cancellation is reasonably low. If a signal is programmatically aborted for 100s of operations you can empty
     * the driver's connection pool.
     *
     * @example
     * ```js
     * const controller = new AbortController();

     * process.on('SIGINT', () => controller.abort(new Error('^C pressed')));

     * const cursor = collection.find({});

     * const documents = await cursor.toArray();

     * you should always assign the result to a new variable in order to get a correctly typed cursor variable.

     *
     * @example
     * ```typescript

     *     change.comment.startsWith('big');
     *     change.operationType === 'insert';
     *     // No need to narrow in code because the generics did that for us!
     *     expectType<Schema>(change.fullDocument);
     *   });
     * ```
     *
     * @remarks
     * When `timeoutMS` is configured for a change stream, it will have different behaviour depending
     * on whether the change stream is in iterator mode or emitter mode. In both cases, a change
     * stream will time out if it does not receive a change event within `timeoutMS` of the last change
     * event.
     *
     * Note that if a change stream is consistently timing out when watching a collection, database or
     * client that is being changed, then this may be due to the server timing out before it can finish
     * processing the existing oplog. To address this, restart the change stream with a higher
     * `timeoutMS`.
     *
     * If the change stream times out the initial aggregate operation to establish the change stream on
     * the server, then the client will close the change stream. If the getMore calls to the server
     * time out, then the change stream will be left open, but will throw a MongoOperationTimeoutError
     * when in iterator mode and emit an error event that returns a MongoOperationTimeoutError in
     * emitter mode.
     *
     * To determine whether or not the change stream is still open following a timeout, check the
     * {@link ChangeStream.closed} getter.
     *
     * @example
     * In iterator mode, if a next() call throws a timeout error, it will attempt to resume the change stream.
     * The next call can just be retried after this succeeds.
     * ```ts
     * const changeStream = collection.watch([], { timeoutMS: 100 });
     * try {
     *     await changeStream.next();
     * } catch (e) {
     *     if (e instanceof MongoOperationTimeoutError && !changeStream.closed) {
     *       await changeStream.next();
     *     }
     *     throw e;
     * }
     * ```
     *
     * @example
     * In emitter mode, if the change stream goes `timeoutMS` without emitting a change event, it will
     * emit an error event that returns a MongoOperationTimeoutError, but will not close the change
     * stream unless the resume attempt fails. There is no need to re-establish change listeners as
     * this will automatically continue emitting change events once the resume attempt completes.
     *
     * ```ts
     * const changeStream = collection.watch([], { timeoutMS: 100 });
     * changeStream.on('change', console.log);
     * changeStream.on('error', e => {
     *     if (e instanceof MongoOperationTimeoutError && !changeStream.closed) {
     *         // do nothing
     *     } else {
     *         changeStream.close();
     *     }
     * });
     * ```

     * Create a new Change Stream, watching for new changes (insertions, updates,
     * replacements, deletions, and invalidations) in this database. Will ignore all
     * changes to system collections.
     *
     * @remarks
     * watch() accepts two generic arguments for distinct use cases:
     * - The first is to provide the schema that may be defined for all the collections within this database
     * - The second is to override the shape of the change stream document entirely, if it is not provided the type will default to ChangeStreamDocument of the first argument
     *
     * @remarks
     * When `timeoutMS` is configured for a change stream, it will have different behaviour depending
     * on whether the change stream is in iterator mode or emitter mode. In both cases, a change
     * stream will time out if it does not receive a change event within `timeoutMS` of the last change
     * event.
     *
     * Note that if a change stream is consistently timing out when watching a collection, database or
     * client that is being changed, then this may be due to the server timing out before it can finish
     * processing the existing oplog. To address this, restart the change stream with a higher
     * `timeoutMS`.
     *
     * If the change stream times out the initial aggregate operation to establish the change stream on
     * the server, then the client will close the change stream. If the getMore calls to the server
     * time out, then the change stream will be left open, but will throw a MongoOperationTimeoutError
     * when in iterator mode and emit an error event that returns a MongoOperationTimeoutError in
     * emitter mode.
     *
     * To determine whether or not the change stream is still open following a timeout, check the
     * {@link ChangeStream.closed} getter.
     *
     * @example
     * In iterator mode, if a next() call throws a timeout error, it will attempt to resume the change stream.
     * The next call can just be retried after this succeeds.
     * ```ts
     * const changeStream = collection.watch([], { timeoutMS: 100 });
     * try {
     *     await changeStream.next();
     * } catch (e) {
     *     if (e instanceof MongoOperationTimeoutError && !changeStream.closed) {
     *       await changeStream.next();
     *     }
     *     throw e;
     * }
     * ```
     *
     * @example
     * In emitter mode, if the change stream goes `timeoutMS` without emitting a change event, it will
     * emit an error event that returns a MongoOperationTimeoutError, but will not close the change
     * stream unless the resume attempt fails. There is no need to re-establish change listeners as
     * this will automatically continue emitting change events once the resume attempt completes.
     *
     * ```ts
     * const changeStream = collection.watch([], { timeoutMS: 100 });
     * changeStream.on('change', console.log);
     * changeStream.on('error', e => {
     *     if (e instanceof MongoOperationTimeoutError && !changeStream.closed) {
     *         // do nothing
     *     } else {
     *         changeStream.close();
     *     }
     * });
     * ```
     * @param pipeline - An array of {@link https://www.mongodb.com/docs/manual/reference/operator/aggregation-pipeline/|aggregation pipeline stages} through which to pass change stream documents. This allows for filtering (using $match) and manipulating the change stream documents.

     * In order to strictly type this function you must provide an interface
     * that represents the effect of your projection on the result documents.
     *
     * By default chaining a projection to your cursor changes the returned type to the generic
     * {@link Document} type.
     * You should specify a parameterized type to have assertions on your final results.
     *
     * @example
     * ```typescript
     * // Best way
     * const docs: FindCursor<{ a: number }> = cursor.project<{ a: number }>({ _id: 0, a: true });
     * // Flexible way
     * const docs: FindCursor<Document> = cursor.project({ _id: 0, a: true });
     * ```
     *
     * @remarks
     *
     * **Note for Typescript Users:** adding a transform changes the return type of the iteration of this cursor,
     * it **does not** return a new instance of a cursor. This means when calling project,
     * you should always assign the result to a new variable in order to get a correctly typed cursor variable.
     * Take note of the following example:
     *
     * @example
     * ```typescript
     * const cursor: FindCursor<{ a: number; b: string }> = coll.find();
     * const projectCursor = cursor.project<{ a: number }>({ _id: 0, a: true });
     * const aPropOnlyArray: {a: number}[] = await projectCursor.toArray();
     *
     * // or always use chaining and save the final cursor
     *
     * const cursor = coll.find().project<{ a: string }>({
     *   _id: 0,
     *   a: { $convert: { input: '$a', to: 'string' }

 *
 * The **MongoClient** class is a class that allows for making Connections to MongoDB.
 *
 * **NOTE:** The programmatically provided options take precedence over the URI options.
 *
 * @remarks
 *
 * A MongoClient is the entry point to connecting to a MongoDB server.
 *
 * It handles a multitude of features on your application's behalf:
 * - **Server Host Connection Configuration**: A MongoClient is responsible for reading TLS cert, ca, and crl files if provided.
 * - **SRV Record Polling**: A "`mongodb+srv`" style connection string is used to have the MongoClient resolve DNS SRV records of all server hostnames which the driver periodically monitors for changes and adjusts its current view of hosts correspondingly.
 * - **Server Monitoring**: The MongoClient automatically keeps monitoring the health of server nodes in your cluster to reach out to the correct and lowest latency one available.
 * - **Connection Pooling**: To avoid paying the cost of rebuilding a connection to the server on every operation the MongoClient keeps idle connections preserved for reuse.
 * - **Session Pooling**: The MongoClient creates logical sessions that enable retryable writes, causal consistency, and transactions. It handles pooling these sessions for reuse in subsequent operations.
 * - **Cursor Operations**: A MongoClient's cursors use the health monitoring system to send the request for more documents to the same server the query began on.
 * - **Mongocryptd process**: When using auto encryption, a MongoClient will launch a `mongocryptd` instance for handling encryption if the mongocrypt shared library isn't in use.
 *
 * There are many more features of a MongoClient that are not listed above.
 *
 * In order to enable these features, a number of asynchronous Node.js resources are established by the driver: Timers, FS Requests, Sockets, etc.
 * For details on cleanup, please refer to the MongoClient `close()` documentation.
 *
 * @example
 * ```ts
 * import { MongoClient } from 'mongodb';
 * // Enable command monitoring for debugging
 * const client = new MongoClient('mongodb://localhost:27017?appName=mflix', { monitorCommands: true });
 * ```

     * Cleans up resources managed by the MongoClient.
     *
     * The close method clears and closes all resources whose lifetimes are managed by the MongoClient.
     * Please refer to the `MongoClient` class documentation for a high level overview of the client's key features and responsibilities.
     *
     * **However,** the close method does not handle the cleanup of resources explicitly created by the user.
     * Any user-created driver resource with its own `close()` method should be explicitly closed by the user before calling MongoClient.close().
     * This method is written as a "best effort" attempt to leave behind the least amount of resources server-side when possible.
     *
     * The following list defines ideal preconditions and consequent pitfalls if they are not met.
     * The MongoClient, ClientSession, Cursors and ChangeStreams all support [explicit resource management](https://www.typescriptlang.org/docs/handbook/release-notes/typescript-5-2.html).
     * By using explicit resource management to manage the lifetime of driver resources instead of manually managing their lifetimes, the pitfalls outlined below can be avoided.
     *
     * The close method performs the following in the order listed:
     * - Client-side:
     *   - **Close in-use connections**: Any connections that are currently waiting on a response from the server will be closed.
     *     This is performed _first_ to avoid reaching the next step (server-side clean up) and having no available connections to check out.
     *     - _Ideal_: All operations have been awaited or cancelled, and the outcomes, regardless of success or failure, have been processed before closing the client servicing the operation.
     *     - _Pitfall_: When `client.close()` is called and all connections are in use, after closing them, the client must create new connections for cleanup operations, which comes at the cost of new TLS/TCP handshakes and authentication steps.
     * - Server-side:
     *   - **Close active cursors**: All cursors that haven't been completed will have a `killCursor` operation sent to the server they were initialized on, freeing the server-side resource.
     *     - _Ideal_: Cursors are explicitly closed or completed before `client.close()` is called.
     *     - _Pitfall_: `killCursors` may have to build a new connection if the in-use closure ended all pooled connections.
     *   - **End active sessions**: In-use sessions created with `client.startSession()` or `client.withSession()` or implicitly by the driver will have their `.endSession()` method called.
     *     Contrary to the name of the method, `endSession()` returns the session to the client's pool of sessions rather than end them on the server.
     *     - _Ideal_: Transaction outcomes are awaited and their corresponding explicit sessions are ended before `client.close()` is called.
     *     - _Pitfall_: **This step aborts in-progress transactions**. It is advisable to observe the outcome of a transaction before closing your client.
     *   - **End all pooled sessions**: The `endSessions` command with all session IDs the client has pooled is sent to the server to inform the cluster it can clean them up.
     *     - _Ideal_: No user intervention is expected.
     *     - _Pitfall_: None.
     *
     * The remaining shutdown is of the MongoClient resources that are intended to be entirely internal but is documented here as their existence relates to the JS event loop.
     *
     * - Client-side (again):
     *   - **Stop all server monitoring**: Connections kept live for detecting cluster changes and roundtrip time measurements are shutdown.
     *   - **Close all pooled connections**: Each server node in the cluster has a corresponding connection pool and all connections in the pool are closed. Any operations waiting to check out a connection will have an error thrown instead of a connection returned.
     *   - **Clear out server selection queue**: Any operations that are in the process of waiting for a server to be selected will have an error thrown instead of a server returned.
     *   - **Close encryption-related resources**: An internal MongoClient created for communicating with `mongocryptd` or other encryption purposes is closed. (Using this same method of course!)
     *
     * After the close method completes there should be no MongoClient related resources [ref-ed in Node.js' event loop](https://docs.libuv.org/en/v1.x/handle.html#reference-counting).
     * This should allow Node.js to exit gracefully if MongoClient resources were the only active handles in the event loop.

     * replacements, deletions, and invalidations) in this cluster. Will ignore all
     * changes to system collections, as well as the local, admin, and config databases.
     *
     * @remarks
     * watch() accepts two generic arguments for distinct use cases:
     * - The first is to provide the schema that may be defined for all the data within the current cluster
     * - The second is to override the shape of the change stream document entirely, if it is not provided the type will default to ChangeStreamDocument of the first argument
     *
     * @remarks
     * When `timeoutMS` is configured for a change stream, it will have different behaviour depending
     * on whether the change stream is in iterator mode or emitter mode. In both cases, a change
     * stream will time out if it does not receive a change event within `timeoutMS` of the last change
     * event.
     *
     * Note that if a change stream is consistently timing out when watching a collection, database or
     * client that is being changed, then this may be due to the server timing out before it can finish
     * processing the existing oplog. To address this, restart the change stream with a higher
     * `timeoutMS`.
     *
     * If the change stream times out the initial aggregate operation to establish the change stream on
     * the server, then the client will close the change stream. If the getMore calls to the server
     * time out, then the change stream will be left open, but will throw a MongoOperationTimeoutError
     * when in iterator mode and emit an error event that returns a MongoOperationTimeoutError in
     * emitter mode.
     *
     * To determine whether or not the change stream is still open following a timeout, check the
     * {@link ChangeStream.closed} getter.
     *
     * @example
     * In iterator mode, if a next() call throws a timeout error, it will attempt to resume the change stream.
     * The next call can just be retried after this succeeds.
     * ```ts
     * const changeStream = collection.watch([], { timeoutMS: 100 });
     * try {
     *     await changeStream.next();
     * } catch (e) {
     *     if (e instanceof MongoOperationTimeoutError && !changeStream.closed) {
     *       await changeStream.next();
     *     }
     *     throw e;
     * }
     * ```
     *
     * @example
     * In emitter mode, if the change stream goes `timeoutMS` without emitting a change event, it will
     * emit an error event that returns a MongoOperationTimeoutError, but will not close the change
     * stream unless the resume attempt fails. There is no need to re-establish change listeners as
     * this will automatically continue emitting change events once the resume attempt completes.
     *
     * ```ts
     * const changeStream = collection.watch([], { timeoutMS: 100 });
     * changeStream.on('change', console.log);
     * changeStream.on('error', e => {
     *     if (e instanceof MongoOperationTimeoutError && !changeStream.closed) {
     *         // do nothing
     *     } else {
     *         changeStream.close();
     *     }
     * });
     * ```
     * @param pipeline - An array of {@link https://www.mongodb.com/docs/manual/reference/operator/aggregation-pipeline/|aggregation pipeline stages} through which to pass change stream documents. This allows for filtering (using $match) and manipulating the change stream documents.
     * @param options - Optional settings for the command
