Trait guion::handler::Handler

pub trait Handler<E>: Sized + 'static where
    E: Env, {
    fn _render(l: Link<E>, r: &mut RenderLink<E>) -> bool;
    fn _event(l: Link<E>, e: (EEvent<E>, &Bounds, u64));
    fn _event_root(l: Link<E>, e: (EEvent<E>, &Bounds, u64));
    fn _size(l: Link<E>) -> ESize<E>;
}

Handlers are stacked inside a Context and any render/event/size action goes through the handler stack
