This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The cancel() method of the ReadableStreamBYOBReader interface cancels the stream, signaling a loss of interest in the stream by a consumer. The supplied reason argument will be given to the underlying source, which may or may not use it.
Note: If the reader is active, the cancel() method behaves the same as that for the associated stream (ReadableStream.cancel()).
Syntax
Promise<reason> readableStreamBYOBReaderInstance.cancel(reason);
Parameters
- reason
- A
DOMStringproviding a human-readable reason for the cancellation.
Return value
A Promise, which fulfills with the value given in the reason parameter.
Exceptions
- TypeError
- The source object is not a
ReadableStreamBYOBReader, or the stream has no owner.
Examples
TBD.
