trait UpgradeToWebSocket extends scaladsl.model.HttpHeader with WebSocketUpgrade
A virtual header that WebSocket requests will contain. Use UpgradeToWebSocket.handleMessagesWith to create a WebSocket handshake response and handle the WebSocket message stream with the given handler.
This low-level API is expected to be replaced by an Attribute in the future.
In any case, you might want to use handleWebSocketMessages instead as documented
at https://pekko.apache.org/docs/pekko-http/current/server-side/websocket-support.html#routing-support
