Trait that a user can implement to specify application behavior, passed into nuuro::run(...).

Required methods

fn advance(&mut self, seconds: f64, ctx: &mut AppContext<A>)

Advances the app state by a given amount of seconds (usually a fraction of a second).

fn key_down(&mut self, key: KeyCode, ctx: &mut AppContext<A>)

Invoked when a key or mouse button is pressed down.

fn render(&mut self, renderer: &mut Renderer<A>, ctx: &AppContext<A>)
