	English ↹ ↵ NBS … “ ” ‘ ’ ﹙-﹚ ‐ – — A WebSocket connection requires a stateful object, represented in Beast by a single class template [link beast.ref.boost__beast__websocket__stream `websocket::stream`]. The interface uses the layered stream model. A websocket stream object contains another stream object, called the "next layer", which it uses to perform I/O. Descriptions of each template parameter follow: 374/10000 · 374

All reads and writes will go through the next layer. This type must meet the requirements of either __SyncStream__, __AsyncStream__, or both, depending on the style of I/O that is to be performed. 314/10000 · 314

Whether or not the stream actually requests or accepts the extension during a handshake depends on a separate configurable option. When the value is `false` the extension is disabled. Streams will never request the extension in the client role or accept a request for the extension in the server role. An additional benefit of disabling the extension is that compilation will be faster, and the resulting program executable will contain less code. 590/10000 · 590

For multi-threaded programs, the `tcp_stream` can be constructed from an executor, in this case a strand.

The function [link beast.ref.boost__beast__get_lowest_layer `get_lowest_layer`] returns the last stream in a stack of layers in a layered stream.
