Hijacking FastHTTP connection to use `coder/websocket`?

[SolomonSklash]

Hello,

Instead of the Go standard net/http, I am using FastHTTP as my webserver, in order to upgrade to websockets using FastHTTP websocket. It currently looks something like this, which is called by the GET handler of my FastHTTP server:

func websocketUpgradeHandler(ctx *fasthttp.RequestCtx) {
	logger.Infof("Received WS request on %s", string(ctx.Path()))

	// Upgrade the connection to a websocket.
	err := websockets.Upgrader.Upgrade(ctx, func(conn *websocket.Conn) {
		// Create a new WS connection object and give it the new WS connection.
		wsConnection := &websockets.WSConnection{Conn: conn}

		// Start the inbound WS worker goroutine.
		wsConnection.WSInboundWorker()
	})
	if err != nil {
		logger.Errorf("Failed to upgrade WS connection: %s", err)
	}
}

According to [#229 (https://github.com//issues/229), this should be doable with using FastHttp's fasthttp#RequestCtx.Hijack. From what I can tell, this will return the request context's underlying net.Conn object.

I am not sure how to make use of this within this websocket library. One total guess is somehow using websocket.Accept, but I don't know how to provide the required ResponseWriter and Request.

Some guidance on this would be much appreciated!
