Detailed Description

class toolbox::traits::enum_wrapper< EnumType >

类型安全的枚举包装器/Type-safe enum wrapper

Template Parameters

EnumType

要包装的枚举类型/Enum type to wrap

enum class Color { Red, Green, Blue };
 
// 创建和使用包装器/Create and use wrapper
enum_wrapper<Color> color(Color::Red);
Color raw_color = color;  // 隐式转换/Implicit conversion
auto value = color.to_underlying();  // 获取底层值/Get underlying value
 
// 编译期检查/Compile-time check
// enum_wrapper<int> error;  // 编译错误：不是枚举类型/Compilation error: not
an enum type
