writable.destroy([error])

• error <Error> 可选，与 'error' 事件一起触发的错误。
• 返回: <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，则可写流已结束，随后对 write() 或 end() 的调用将导致 ERR_STREAM_DESTROYED 错误。 这是销毁流的破坏性和直接的方式。 先前对 write() 的调用可能没有排空，并且可能触发 ERR_STREAM_DESTROYED 错误。 如果数据应该在关闭之前刷新，或者在销毁流之前等待 'drain' 事件，则使用 end() 而不是销毁。 实现者不应覆盖此方法，而应实现 writable._destroy()。

• error <Error> Optional, an error to emit with 'error' event.
• Returns: <this>

Destroy the stream. Optionally emit an 'error' event, and emit a 'close' event (unless emitClose is set to false). After this call, the writable stream has ended and subsequent calls to write() or end() will result in an ERR_STREAM_DESTROYED error. This is a destructive and immediate way to destroy a stream. Previous calls to write() may not have drained, and may trigger an ERR_STREAM_DESTROYED error. Use end() instead of destroy if data should flush before close, or wait for the 'drain' event before destroying the stream. Implementors should not override this method, but instead implement writable._destroy().
