writable._destroy(err, callback)

• err <Error> 可能的错误。

  ¥err <Error> A possible error.

• callback <Function> 采用可选的错误参数的回调函数。

  ¥callback <Function> A callback function that takes an optional error argument.

_destroy() 方法被 writable.destroy() 调用。它可以被子类覆盖，但不能直接调用。此外，callback 不应与 async/await 混合使用，一旦它在 promise 被解析时执行。

¥The _destroy() method is called by writable.destroy(). It can be overridden by child classes but it must not be called directly. Furthermore, the callback should not be mixed with async/await once it is executed when a promise is resolved.
