buildRouteHandler builds the single mux handler that is a chain of the middleware stack as defined by calls to Use () and the tree router ( Mux ) itself . After this point no other middlewares can be registered on this Mux s stack . But you can still compose additional middlewares via Group () s or using a chained middleware handler .
