Les points d’entrée sont setup(), draw() et run() dans l’exemple Python publié ; reproduisez d’abord le NameError et examinez le nommage exporté de la Rust Processing API pour frame_rate. Confirmez si l’exemple ou l’API est en cause, puis vérifiez que l’exemple démarre et s’exécute sans l’erreur de nom non défini.
