Enum Error 

pub enum Error {
    UnknownProvider(String),
    ProviderDisabled(String),
    Unsupported {
        provider: String,
        capability: &'static str,
    },
    MissingConfig(&'static str),
    Api {
        status: u16,
        message: String,
    },
    Http(Error),
    Parse(String),
    MissingField(&'static str),
}

Variants

UnknownProvider(String)

ProviderDisabled(String)

厂商或模态未在 Cargo feature 中启用（例如启了 rerank 但未启 aliyun 仍选阿里云）。

Unsupported

该厂商在此模态下无实现，或能力仍为占位（如语音工厂）。

Fields

provider: String

capability: &'static str

MissingConfig(&'static str)

Api

上游 HTTP 非 2xx；message 来自响应体（经各模态解析或拼接）。未知模型、鉴权失败、参数错误等通常落在此变体，而非单独的「模型」枚举分支。

Fields

status: u16

message: String

Http(Error)

Parse(String)

MissingField(&'static str)

Implementations

impl Error

pub fn is_retryable(&self) -> bool

是否属于可安全重试的错误（幂等前提下）。

以下情况返回 true：

• HTTP 429 Too Many Requests
• HTTP 5xx 服务端错误
• reqwest 网络层错误（连接超时、连接重置等）

pub fn requires_human(&self) -> bool

是否需要人工介入（鉴权失败、权限不足、资源不存在等）。

以下情况返回 true：

• HTTP 401 Unauthorized
• HTTP 403 Forbidden
• HTTP 404 Not Found

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

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<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
