Module controller_registry 

Controller Type Registry for runtime controller resolution

This module implements a compile-time controller type registry that enables runtime controller instantiation from string names, overcoming Rust’s type system limitations with trait object resolution.

Architecture

• ControllerTypeRegistry: Global registry of controller factory functions
• ControllerFactory: Type-erased factory function for controller creation
• CONTROLLER_TYPE_REGISTRY: Thread-safe global instance

Usage

Controllers are automatically registered via the #[controller] macro:

#[controller("/api/users")]
pub struct UserController;
 
// Macro generates registration call:
// CONTROLLER_TYPE_REGISTRY.register("UserController", || Box::new(UserController::new()));

The registry then enables runtime resolution:

let controller = CONTROLLER_TYPE_REGISTRY.create_controller("UserController")?;
