Function miniquad::start

pub fn start<F>(conf: Conf, f: F) where
    F: 'static + FnOnce(&mut Context) -> Box<dyn EventHandler>, 

Start miniquad. Initialization callback will be called when miniquad’s Context is ready. User can take ownership on Context and store it in user Code. Or return it back to miniquad and give miniquad ownership on Context.

Variant wth EventHandler:

struct Stage;

impl EventHandler for Stage {
    fn update(&mut self, _ctx: &mut Context) {}
    fn draw(&mut self, _ctx: &mut Context) {}
}
fn main() {
    miniquad::start(conf::Conf::default(), |ctx| UserData::owning(Stage, ctx));
}

Variant wth EventHandlerFree:

struct Stage {
    ctx: Context,
}
impl EventHandlerFree for Stage {
    fn update(&mut self) {}
    fn draw(&mut self) {}
}
fn main() {
    miniquad::start(conf::Conf::default(), |ctx| UserData::free(Stage { ctx }));
}
