错误码转换 trait — 连接业务错误枚举与统一 AppError 的桥梁。

通过 #[derive(CodeMsg)] 宏自动生成实现，业务层无需手写。

Required Methods

fn err_code(self) -> AppErrCode

将自身转换为归一化的 AppErrCode 值

Provided Methods

fn domain(self) -> &'static str

fn code(self) -> i32

fn message(self) -> &'static str

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
