readable.destroy([error])

• error <Error> 将作为 'error' 事件中的有效负载传递的错误

  ¥error <Error> Error which will be passed as payload in 'error' event

• 返回：<this>

  ¥Returns: <this>

销毁流可选地触发 'error' 事件，并且触发 'close' 事件（除非 emitClose 设置为 false）。在此调用之后，可读流将释放任何内部资源，随后对 push() 的调用将被忽略。

¥Destroy the stream. Optionally emit an 'error' event, and emit a 'close' event (unless emitClose is set to false). After this call, the readable stream will release any internal resources and subsequent calls to push() will be ignored.

一旦 destroy() 被调用，任何进一步的调用都将是空操作，除了来自 _destroy() 的其他错误可能不会作为 'error' 触发。

¥Once destroy() has been called any further calls will be a no-op and no further errors except from _destroy() may be emitted as 'error'.

实现者不应覆盖此方法，而应实现 readable._destroy()。

¥Implementors should not override this method, but instead implement readable._destroy().
