Struct DispatcherRegistration 

pub struct DispatcherRegistration {
    pub type_name: &'static str,
    pub role: ComponentRole,
    pub register_fn: fn(&mut Engine),
}

Per-(component_type, role) inventory carrying a per-T dispatcher-registration fn pointer. Each role derive emits one of these alongside ComponentRoleBinding; install() walks the channel + calls register_fn(engine) for each bound concrete so the engine learns about every role dispatcher without the install path needing the typed &T.

Fields

type_name: &'static str

ConcreteComponent::TYPE_NAME — the join key.

role: ComponentRole

The role the registration corresponds to.

register_fn: fn(&mut Engine)

Per-T registration callback. The derive captures T at the emit site and the fn body calls engine.register_<role>_dispatcher::<T>().
