To invoke the customization point, first bring the default implementation into scope with a `using` statement. Then call the customization point without namespace qualification, allowing argument-dependent lookup to take effect:

When the implementation invokes the asynchronous teardown function, it always uses an invokable completion handler. It is not necessary to specify the return type customization when creating user-defined overloads of `async_teardown`.

To provide overloads of teardown for a user-defined type, simply declare the two free functions with the correct signature, accepting a reference to the user-defined type as the stream parameter:

The implementation provides suitable overloads of the teardown customization points when websocket streams are instantiated using the Asio types __socket__ or __ssl_stream__ for the next layer. In this case no user action is required. However, when the websocket stream is instantiated for a user-defined type, compile errors will result if the customization points are not provided for the user defined type. Furthermore, user-defined types that wrap one of the Asio objects mentioned earlier may wish to invoke a teardown customization point for the wrapped object. This is how those tasks are accomplished.

The WebSocket protocol requirements described in rfc6455 section 7.1.1 outline an operation described as [@https://tools.ietf.org/html/rfc6455#section-7.1.1 ['Close the WebSocket Connection]]. This operation cleanly discards bytes remaining at receiving endpoints and also closes the underlying TCP/IP connection. Orderly shutdowns are always preferred; for TLS or SSL streams, a protocol-level shutdown is desired. This presents a small issue for the [link beast.ref.boost__beast__websocket__stream `stream`] implementation: the stream's `NextLayer` template type requires only __SyncStream__ or __AsyncStream__, but those concepts do not support the operations to shut down the connection.
