import { Request } from "https://deno.land/x/oak@v17.0.0/request.ts";
Take the current request and upgrade it to a web socket, returning a web
standard WebSocket object.
If the underlying server abstraction does not support upgrades, this will throw.
![WARNING] This is not intended for direct use, as it will not manage the websocket in the overall context or ensure that additional middleware does not attempt to respond to the request.
Parameters
optional
options: UpgradeWebSocketOptions
