route name

To be available to know the name of the route within the handler, the .Name method can be used, example:

router := violetear.New()

router.Handle("*", catchAll, "ALL").Name("*")
router.HandleFunc("/post", methodPOST, "POST").Name("post")
router.HandleFunc("/get", methodALL, "GET").Name("get")
router.HandleFunc("/:any", methodRX).Name("rx")

To retrieve the name within the handler this could be used:

func theHandler(w http.ResponseWriter, r *http.Request) {
    endpoint := violetear.GetRouteName(r)
	fmt.Fprintf(w, "my name is: %s!", endpoint)
}

This is useful when instrumenting your code with tools like prometheus.

GetError()

Handle and HandleFunc return a *Trie this is needed to be available to set a Name per route, therefore to know if an error occurred when creating the route the method GetError() can be used, for example:

router.Handle("*", catchAll, "ALL").Name("*")
if err := router.GetError(); err != nil {
    log.Fatal(err)
}
