registro Vamos a diseñar una sencilla utilidad de registro mediante un trait Logger con un método log. El código que podría registrar su progreso puede usar &impl Logger. En las pruebas, esta acción colocaría con el nivel de verbosidad determinado. fn log(&self, verbosity: u8, message: impl Display); } struct StderrLogger; impl Logger for StderrLogger { fn log(&self, verbosity: u8, message: impl Display) ("verbosidad={verbosity}: {message}"); } } fn do_things(logger: &impl Logger) { logger.log(5, "Para tu información"); logger.log(2, "Oh, oh"); } // TAREA: Define e implementa `VerbosityFilter`. fn main() {
