Enum ResourceRequest 

pub enum ResourceRequest<T: ActorEntity> {
    Create {
        params: T::Create,
        respond_to: Response<T::Id>,
    },
    Get {
        id: T::Id,
        respond_to: Response<Option<T>>,
    },
    Update {
        id: T::Id,
        update: T::Update,
        respond_to: Response<T>,
    },
    Delete {
        id: T::Id,
        respond_to: Response<()>,
    },
    Action {
        id: T::Id,
        action: T::Action,
        respond_to: Response<T::ActionResult>,
    },
}

Internal message type sent to the actor to request operations.

Resource-Oriented Architecture

This enum implements a Resource-Oriented design pattern where each actor manages a specific type of resource (the ActorEntity). Instead of defining ad-hoc messages for every operation, we standardize around a set of lifecycle operations that apply to almost any persistent resource.

The CRUD Pattern

The variants of this enum map directly to standard CRUD (Create, Read, Update, Delete) operations, plus a custom Action variant for resource-specific logic that doesn’t fit the CRUD model.

• Create: Lifecycle start. Uses ActorEntity::Create to initialize a new resource.
• Get (Read): Retrieval. Fetches the current state of the resource by ID.
• Update: State mutation. Uses ActorEntity::Update to modify an existing resource.
• Delete: Lifecycle end. Removes the resource.
• Action: Extensibility. Executes a custom ActorEntity::Action.

Entity Interaction

This type is generic over T: ActorEntity. It uses the associated types defined in the ActorEntity trait (like Create, Update, Action) to ensure type safety for every operation. This guarantees that you can’t send a “User Create” payload to a “Product” actor.
