pub fn application<State, Message, Theme, Renderer>(
    title: impl Title<State>,
    update: impl Update<State, Message>,
    view: impl for<'a> View<'a, State, Message, Theme, Renderer>,
) -> Application<impl Program<State = State, Message = Message, Theme = Theme>>
where

    Message: Send + Debug + 'static,
    Theme: Default + DefaultStyle,

pub fn main() -> iced::Result {
    iced::application("A counter", update, view).run()
}

#[derive(Debug, Clone)]
enum Message {
    Increment,
}

fn update(value: &mut u64, message: Message) {
    match message {
        Message::Increment => *value += 1,
    }
}

fn view(value: &u64) -> Column<Message> {
    column![
        text(value),
        button("+").on_press(Message::Increment),
    ]
}
