Example

The following example examines how resync.Once could be used in a HTTP server situation.

// use it just like sync.Once
var once resync.Once

// handle a web request
func handleRequest(w http.ResponseWriter, r *http.Request) {
	once.Do(func(){
		// load templates or something
	})
	// TODO: respond
}

// handle some request that indicates things have changed
func handleResetRequest(w http.ResponseWriter, r *http.Request) {
	once.Reset() // call Reset to cause initialisation to happen again above
}
