Struct BaseException 

pub struct BaseException {
    pub code: i32,
    pub msg: String,
    pub message_key: Option<String>,
}

BaseException — 对齐 PHP app\common\exception\BaseException

PHP 原始实现：

class BaseException extends Exception {
    public $code = 0;
    public $message = 'invalid parameters';
    public function __construct($params = []) {
        if (array_key_exists('code', $params)) { $this->code = $params['code']; }
        if (array_key_exists('msg', $params)) { $this->message = $params['msg']; }
    }
}

Fields

code: i32

错误码（对齐 PHP $code）

msg: String

错误消息（对齐 PHP $message，PHP 用 msg 键传入）

message_key: Option<String>

本地化消息键（i18n 翻译用，默认 None 表示 msg 已是最终文案）

设置后由上层（如 sz-rust-mvc-facade 的 i18n_error::localize_exception） 通过 i18n 模块翻译为指定语言文案。

Implementations

impl BaseException

pub fn new(code: ErrorCode, msg: impl Into<String>) -> Self

创建 BaseException（对齐 PHP new BaseException(['code' => x, 'msg' => y])）

pub fn with_message_key(self, key: impl Into<String>) -> Self

设置本地化消息键（i18n 翻译用）

pub fn message_key(&self) -> Option<&str>

获取本地化消息键（无则 None）

pub fn not_login(msg: impl Into<String>) -> Self

未登录快捷构造（对齐 PHP throw new BaseException(['code' => -1, 'msg' => 'not_login'])）

pub fn user_not_found(msg: impl Into<String>) -> Self

用户不存在快捷构造（对齐 PHP throw new BaseException(['msg' => '没有找到用户信息', 'code' => -2])）

pub fn user_disabled(msg: impl Into<String>) -> Self

用户已禁用快捷构造（对齐 PHP throw new BaseException(['msg' => '您已离职', 'code' => -3])）

pub fn failed(msg: impl Into<String>) -> Self

失败快捷构造（对齐 PHP renderError('error')）

pub fn forbidden(msg: impl Into<String>) -> Self

无权限快捷构造

pub fn not_found(msg: impl Into<String>) -> Self

资源不存在快捷构造

pub fn validate_failed(msg: impl Into<String>) -> Self

验证失败快捷构造

pub fn to_json(&self) -> Value

转为 JSON 响应（对齐 PHP renderJson(code, msg, data)）

Trait Implementations

impl Clone for BaseException

fn clone(&self) -> BaseException

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BaseException

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for BaseException

fn default() -> Self

Returns the “default value” for a type.

impl Display for BaseException

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for BaseException

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
