Enum Error 

pub enum Error {
    Config(String),
    Plugin {
        name: String,
        source: Box<dyn Error + Send + Sync>,
    },
    Server(String),
    Io(Error),
    Template(String),
    Msg(String),
}

框架统一错误类型

所有模块皆通过此类型返回错误，是 alun 生态的错误“语言“。 支持从 std::io::Error、String、&str、ApiError 自动转换。

示例

fn load_config() -> alun_core::Result<AppConfig> {
    Err(alun_core::Error::Config("config.toml 格式错误".into()))
}

Variants

Config(String)

配置加载或解析错误（如 TOML 格式错误、必填字段缺失）

Plugin

插件生命周期错误（携带插件名和底层错误源）

Fields

name: String

出错的插件名称

source: Box<dyn Error + Send + Sync>

底层错误源

Server(String)

服务器启动或运行失败（如端口被占用）

Io(Error)

IO 操作错误（如文件读写失败、网络故障）

Template(String)

模板渲染错误

Msg(String)

通用业务错误消息

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<&str> for Error

fn from(s: &str) -> Error

Converts to this type from the input type.

impl From<ApiError> for Error

fn from(e: ApiError) -> Error

Converts to this type from the input type.

impl From<Error> for ApiError

fn from(e: Error) -> ApiError

Converts to this type from the input type.

impl From<Error> for Error

fn from(e: Error) -> Error

Converts to this type from the input type.

impl From<String> for Error

fn from(s: String) -> Error

Converts to this type from the input type.
