Enum ApiError 

pub enum ApiError {
    Http {
        status: StatusCode,
        text: String,
    },
    Reqwest(Error),
    Json(Error),
    EventSource(String),
    Io(Error),
    Other(String),
    Unknown,
}

统一的错误类型，覆盖常见的错误来源并保留一个通用字符串变体用于快速转换。

Variants

Http

HTTP 层面的失败（当我们想保留状态码与响应文本时使用）

Fields

status: StatusCode

text: String

Reqwest(Error)

reqwest 网络/请求错误

Json(Error)

serde_json 解析/序列化错误

EventSource(String)

EventSource / SSE 处理错误（来自 eventsource-stream crate） 以字符串形式保存错误信息（避免直接依赖具体 crate 的错误类型签名）

Io(Error)

IO 错误（保底）

Other(String)

通用字符串错误（方便从 String / &str 直接转换）

Unknown

未知或占位错误

Trait Implementations

impl Debug for ApiError

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

Formats the value using the given formatter.

impl Display for ApiError

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

Formats the value using the given formatter.

impl Error for ApiError

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 ApiError

fn from(s: &str) -> Self

impl From<Error> for ApiError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for ApiError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for ApiError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<String> for ApiError

fn from(s: String) -> Self

Converts to this type from the input type.
