Provider 错误（增强版）

变体说明

• Network: 网络错误（可重试）
• Api: API 错误（根据状态码判断）
• Authentication: 认证错误（不可重试）
• RateLimit: 限流错误（可重试，带等待时间）
• Timeout: 超时错误（可重试）
• Model: 模型错误
• Message: 通用错误（向后兼容）

Trait Implementations

impl Debug for ProviderError

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

Formats the value using the given formatter.

impl DiagnosticError for ProviderError

fn diagnostic(&self) -> ErrorDiagnostic

获取错误的诊断信息

fn is_retriable(&self) -> bool

判断是否可重试

fn category(&self) -> ErrorCategory

获取错误类别

impl Display for ProviderError

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

impl Error for ProviderError

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.
