Optional rawEnabling the raw option will return a Node.js Buffer which is allocated using allocUnsafe API.启用raw选项将返回使用allocUnsafe API分配的Node.js缓冲区。
See this section from the Node.js Docs here for more detail about what "unsafe" refers to in this context.请参阅Node.js文档中的这一部分，了解有关“不安全”在本文中所指内容的更多详细信息。
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:如果您需要维护自己的可编辑字节克隆，以延长进程的使用寿命，建议您分配自己的缓冲区并克隆内容：
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
