sz-rust-addons-loader 0.3.0

//! # SZ-Rust Addons Loader — 插件加载器
//!
//! 对标 PHP `zzstudio/think-addons` 的 Rust 实现，提供插件发现/清单解析/注册/路由解析能力。
//!
//! ## PHP 对齐
//!
//! | PHP 模块 | Rust 模块 | 子任务 |
//! |----------|----------|--------|
//! | `think\addons\Service` | `loader::AddonLoader` | 10.1 |
//! | `think\Addons::getInfo()` | `manifest::parse_manifest` | 10.1 |
//! | `spl_autoload_register`（helper.php） | `autoload::AddonAutoload` | 10.1 |
//! | 隐式插件状态管理 | `registry::AddonRegistry` | 10.2 |
//! | `think\addons\Route::execute` | `route::parse_route` | 10.3 |
//! | `think\Route::resource` | `resource::build_resource_routes` | 10.3.5 |
//!
//! ## 模块结构
//!
//! ```text
//! sz-rust-addons-loader/
//! ├── Cargo.toml
//! └── src/
//!     ├── lib.rs          # 主入口（重导出）
//!     ├── error.rs        # 错误类型
//!     ├── loader.rs       # AddonLoader（对齐 Service.php）
//!     ├── manifest.rs     # 清单解析（对齐 Addons::getInfo）
//!     ├── autoload.rs     # 自动加载（对齐 spl_autoload_register）
//!     ├── registry.rs     # 注册中心（对齐插件状态管理）
//!     ├── route.rs        # 路由解析（对齐 Route::execute）
//!     └── resource.rs     # 资源路由注入（对齐 Route::resource）
//! ```
//!
//! ## 用法
//!
//! ```rust,ignore
//! use sz_rust_addons_loader::loader::AddonLoader;
//!
//! let loader = AddonLoader::new("/path/to/addons");
//! let errors = loader.register().unwrap();
//! // errors 包含解析失败的插件错误（不中断整体扫描）
//!
//! let route = loader.parse_route("/addons/operate/Order/index").unwrap();
//! assert_eq!(route.addon, "operate");
//! assert_eq!(route.controller, "Order");
//! assert_eq!(route.action, "index");
//! ```
//!
//! ## 不支持（与 PHP 差异）
//!
//! - **不实际加载 PHP 文件**：Rust 无法直接执行 PHP，仅解析 `$info` 数组
//! - **不实现钩子自动扫描**：PHP 通过反射收集 Plugin.php 非基类方法作为钩子，Rust 侧需调用方显式注册
//! - **不实现 `service.ini` 容器绑定**：Rust 侧无容器概念，由调用方根据需要处理
//! - **不实现 `_empty` 兜底方法**：对齐 PHP `is_callable([$instance, '_empty'])`，但需调用方实现
