+ * [Internal] Bridge between StreamInterface from PSR-7 and ReadableStreamInterface from ReactPHP
+ *
+ * This class is used in the server to stream the body of an incoming response
+ * from the client. This allows us to stream big amounts of data without having
+ * to buffer this data. Similarly, this used to stream the body of an outgoing
+ * request body to the client. The data will be sent directly to the client.
+ *
+ * Note that this is an internal class only and nothing you should usually care
+ * about. See the `StreamInterface` and `ReadableStreamInterface` for more
+ * details.
