sz-rust-cli 0.2.1

//! 代码生成模板 — 对齐 PHP `think\console\command\make\stubs\*.stub`
//!
//! ## PHP 对齐
//!
//! PHP `Make::buildClass()` 读取 stub 文件并替换占位符：
//!
//! - `{%className%}`：类名（如 `User`）
//! - `{%namespace%}`：命名空间（如 `app\model` 或 `app\controller`）
//! - `{%actionSuffix%}`：方法后缀（PHP 默认空字符串）
//! - `{%app_namespace%}`：应用命名空间（PHP 默认 `app`）
//!
//! Rust 端使用常量字符串存储模板，通过 `str::replace` 替换占位符。
//!
//! ## 模板列表
//!
//! | 常量 | 对齐 PHP stub | 用途 |
//! |------|--------------|------|
//! | `MODEL_STUB` | `model.stub` | `make:model` 生成 Model 骨架 |
//! | `CONTROLLER_STUB` | `controller.stub` | `make:controller` 生成 7 方法 Controller |
//! | `CONTROLLER_API_STUB` | `controller.api.stub` | `make:controller --api` 生成 5 方法 API Controller |
//! | `CONTROLLER_PLAIN_STUB` | `controller.plain.stub` | `make:controller --plain` 生成空 Controller |
//! | `MIGRATION_UP_STUB` | — | `make:migration` 生成 up SQL |
//! | `MIGRATION_DOWN_STUB` | — | `make:migration` 生成 down SQL |
