12 * [Internal] Bridge between an empty StreamInterface from PSR-7 and ReadableStreamInterface from ReactPHP
13 *
14 * This class is used in the server to represent an empty body stream of an
15 * incoming response from the client. This is similar to the `HttpBodyStream`,
16 * but is specifically designed for the common case of having an empty message
17 * body.
18 *
19 * Note that this is an internal class only and nothing you should usually care
20 * about. See the `StreamInterface` and `ReadableStreamInterface` for more
21 * details.
