* @remarks
*
* **Note** Cursors use `null` internally to indicate that there are no more documents in the cursor. Providing a mapping
* function that maps values to `null` will result in the cursor closing itself before it has finished iterating
* all documents. This will **not** result in a memory leak, just surprising behavior. For example:
*
* ```typescript
* const cursor = collection.find({});
* cursor.map(() => null);
*
* const documents = await cursor.toArray();
* // documents is always [], regardless of how many documents are in the collection.
* ```

*
* ```typescript
* const cursor = collection.find({});
* cursor.map(() => '');
*
* const documents = await cursor.toArray();
* // documents is now an array of empty strings
* ```
*
* **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 map,
* 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<Document> = coll.find();
* const mappedCursor: FindCursor<number> = cursor.map(doc => Object.keys(doc).length);
* const keyCounts: number[] = await mappedCursor.toArray(); // cursor.toArray() still returns Document[]

* Enabling the raw option will return a [Node.js Buffer](https://nodejs.org/api/buffer.html)

* See this section from the [Node.js Docs here](https://nodejs.org/api/buffer.html#what-makes-bufferallocunsafe-and-bufferallocunsafeslow-unsafe)
* for more detail about what "unsafe" refers to in this context.
* If you need to maintain your own editable clone of the bytes returned for an extended life time of the process, it is recommended you allocate
* your own buffer and clone the contents:
*
* @example
* ```ts
* const raw = await collection.findOne({}, { raw: true });
* const myBuffer = Buffer.alloc(raw.byteLength);
* myBuffer.set(raw, 0);
* // Only save and use `myBuffer` beyond this point
* ```
*
* @remarks
* Please note there is a known limitation where this option cannot be used at the MongoClient level (see [NODE-3946](https://jira.mongodb.org/browse/NODE-3946)).
* It does correctly work at `Db`, `Collection`, and per operation the same as other BSON options work.
