error() method of the
ReadableStreamDefaultController interface causes any future interactions
with the associated stream to error.
error() method can be called
more than once, and can be called when the stream is not readable.
- The error you want future interactions to fail with.
- The source object is not a
ReadableStreamDefaultController, or the stream is not readable for some other reason.
The A readable
stream with an underlying push source and backpressure support example in the spec
provides a good example of using
ReadablestreamDefaultController.desiredSize to manually detect when the
stream is full and apply backpressure, and also of using
manually trigger a stream error if another part of the system it relies on fails.
The definition of 'error()' in that specification.
