Trait Sketch

pub trait Sketch: Sized {
    // Required methods
    fn name(&self) -> &str;
    fn description(&self) -> &str;
    fn model(app: &App) -> Self;
    fn update(&mut self, app: &App, update: Update);
    fn view(&self, app: &App, frame: Frame<'_>);
}

Trait for nannou sketches that can be discovered and run.

Implementing this trait allows sketches to be registered and managed by the Sketchbook.
