    stream: Handle<*mut JSObject>,
    mode: *mut ReadableStreamMode

Expand description

Returns the stream’s ReadableStreamMode. If the mode is |Byte| or |ExternalSource|, it’s possible to acquire a BYOB reader for more optimized operations.

Asserts that |stream| is a ReadableStream object or an unwrappable wrapper for one.
