Enum CompRef 

pub enum CompRef {
    Factory(Arc<dyn Fn(&Store) -> Arc<dyn Any + Send + Sync> + Send + Sync>),
    Cached(Arc<dyn Any + Send + Sync>),
}

存储单元：

• Factory(Arc<dyn Fn>) → 存工厂闭包，prototype 每次注入时调用
• Cached(Arc<dyn Any>) → 已实例化的单例（擦除类型）

Variants

Factory(Arc<dyn Fn(&Store) -> Arc<dyn Any + Send + Sync> + Send + Sync>)

工厂闭包：Prototype 作用域，每次注入调用

Cached(Arc<dyn Any + Send + Sync>)

已缓存的实例：Singleton 作用域

Trait Implementations

fn clone(&self) -> Self

fn clone_from(&mut self, source: &Self)
