desiredSize read-only property of the
ReadableStreamDefaultController interface returns the desired size
required to fill the stream's internal queue.
var desiredSize = readableStreamDefaultController.desiredSize;
An integer. Note that this can be negative if the queue is over-full.
The A readable
stream with an underlying push source and backpressure support example in the spec
provides a good example of using
desiredSize to manually detect when the
stream is full and apply backpressure, and also of using
ReadablestreamDefaultController.error() to manually trigger a stream
error if another part of the system it relies on fails.
The definition of 'desiredSize' in that specification.
