* with the source's error, or with any error that occurs during | |
* aborting the destination. | |

* An error in destination will cancel this source readable stream, | |
* unless preventCancel is truthy. The returned promise will be rejected | |
* with the destination's error, or with any error that occurs during | |
* canceling the source. | |
* | |
* When this source readable stream closes, destination will be closed, | |
* unless preventClose is truthy. The returned promise will be fulfilled | |
* once this process completes, unless an error is encountered while | |
* closing the destination, in which case it will be rejected with that | |
* error. | |
* | |
* If destination starts out closed or closing, this source readable | |
* stream will be canceled, unless preventCancel is true. The returned | |
* promise will be rejected with an error indicating piping to a closed | |
* stream failed, or with any error that occurs during canceling the | |
* source. | |
* | |
* The signal option can be set to an AbortSignal to allow aborting an | |
* ongoing pipe operation via the corresponding AbortController. In this | |
* case, this source readable stream will be canceled, and destination | |
* aborted, unless the respective options preventCancel or preventAbort | |
* are set. | |
