ReadableStreamBYOBReader
Background
BYOB is an abbreviation of bring your own buffer. A ReadableStreamBYOBReader allows reading into a developer-supplied buffer, thus minimizing copies.
An instance of ReadableStreamBYOBReader is functionally identical to ReadableStreamDefaultReader with the exception of the read method.
A ReadableStreamBYOBReader is not instantiated via its constructor. Rather, it is retrieved from a ReadableStream:
Methods
-
read(bufferArrayBufferView):Promise<ReadableStreamBYOBReadResult>- Returns a promise with the next available chunk of data read into a passed-in buffer.
-
readAtLeast(minBytes, bufferArrayBufferView):Promise<ReadableStreamBYOBReadResult>- Returns a promise with the next available chunk of data read into a passed-in buffer. The promise will not resolve until at least
minByteshave been read.
