    type Router

    type Router struct {
    	// contains filtered or unexported fields

      Router registers routes to be matched and dispatches a handler.

      func NewRouter

      func NewRouter(opts ...RouterOption) *Router

        NewRouter returns a new router instance traced with the global tracer.

        func (*Router) ServeHTTP

        func (r *Router) ServeHTTP(w http.ResponseWriter, req *http.Request)

          ServeHTTP dispatches the request to the handler whose pattern most closely matches the request URL. We only need to rewrite this function to be able to trace all the incoming requests to the underlying multiplexer

          func (*Router) SkipClean

          func (r *Router) SkipClean(value bool) *Router

            SkipClean defines the path cleaning behaviour for new routes. The initial value is false. Users should be careful about which routes are not cleaned

            When true, if the route path is "/path//to", it will remain with the double slash. This is helpful if you have a route like: /fetch/

            When false, the path will be cleaned, so /fetch/ will become /fetch/http/

            func (*Router) StrictSlash

            func (r *Router) StrictSlash(value bool) *Router

              StrictSlash defines the trailing slash behavior for new routes. The initial value is false.

              When true, if the route path is "/path/", accessing "/path" will perform a redirect to the former and vice versa. In other words, your application will always see the path as specified in the route.

              When false, if the route path is "/path", accessing "/path/" will not match this route and vice versa.

              The re-direct is a HTTP 301 (Moved Permanently). Note that when this is set for routes with a non-idempotent method (e.g. POST, PUT), the subsequent re-directed request will be made as a GET by most clients. Use middleware or client settings to modify this behaviour as needed.

              Special case: when a route sets a path prefix using the PathPrefix() method, strict slash is ignored for that route because the redirect behavior can't be determined from a prefix alone. However, any subrouters created from that route inherit the original StrictSlash setting.

              func (*Router) UseEncodedPath

              func (r *Router) UseEncodedPath() *Router

                UseEncodedPath tells the router to match the encoded original path to the routes. For eg. "/path/foo%2Fbar/to" will match the path "/path/{var}/to".

                If not called, the router will match the unencoded path to the routes. For eg. "/path/foo%2Fbar/to" will match the path "/path/foo/bar/to"

                type RouterOption

                type RouterOption func(*routerConfig)

                  RouterOption represents an option that can be passed to NewRouter.

                  func NoDebugStack

                  func NoDebugStack() RouterOption

                    NoDebugStack prevents stack traces from being attached to spans finishing with an error. This is useful in situations where errors are frequent and performance is critical.

                    func WithAnalytics

                    func WithAnalytics(on bool) RouterOption

                      WithAnalytics enables Trace Analytics for all started spans.

                      func WithAnalyticsRate

                      func WithAnalyticsRate(rate float64) RouterOption

                        WithAnalyticsRate sets the sampling rate for Trace Analytics events correlated to started spans.

                        func WithIgnoreRequest

                        func WithIgnoreRequest(f func(*http.Request) bool) RouterOption

                          WithIgnoreRequest holds the function to use for determining if the incoming HTTP request tracing should be skipped.

                          func WithResourceNamer

                          func WithResourceNamer(namer func(router *Router, req *http.Request) string) RouterOption

                            WithResourceNamer specifies a quantizing function which will be used to obtain the resource name for a given request.

                            func WithServiceName

                            func WithServiceName(name string) RouterOption

                              WithServiceName sets the given service name for the router.

                              func WithSpanOptions

                              func WithSpanOptions(opts ...ddtrace.StartSpanOption) RouterOption

                                WithSpanOptions applies the given set of options to the spans started by the router.
