Trait ErrorExt 

pub trait ErrorExt<T> {
    // Required methods
    fn bad_request(self) -> HttpResult<T>;
    fn unauthorized(self) -> HttpResult<T>;
    fn forbidden(self) -> HttpResult<T>;
    fn not_found(self) -> HttpResult<T>;
    fn internal_error(self) -> HttpResult<T>;
    fn with_http_error(self, error: HttpError) -> HttpResult<T>;
    fn map_http_error<F>(self, f: F) -> HttpResult<T>
       where F: FnOnce(String) -> HttpError;
}

错误扩展 trait

为 Result 类型提供便捷的错误转换方法。

Required Methods

fn bad_request(self) -> HttpResult<T>

将错误转换为验证错误 (400)

fn unauthorized(self) -> HttpResult<T>

将错误转换为认证错误 (401)

fn forbidden(self) -> HttpResult<T>

将错误转换为权限错误 (403)

fn not_found(self) -> HttpResult<T>

将错误转换为资源未找到错误 (404)

fn internal_error(self) -> HttpResult<T>

将错误转换为内部服务器错误 (500)

fn with_http_error(self, error: HttpError) -> HttpResult<T>

使用自定义 HttpError 转换

fn map_http_error<F>(self, f: F) -> HttpResult<T>

where F: FnOnce(String) -> HttpError,

使用错误消息转换函数

Dyn Compatibility

This trait is not dyn compatible.

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