Struct ErrorDiagnostic 

pub struct ErrorDiagnostic {
    pub kind: String,
    pub message: String,
    pub retriable: bool,
    pub source: Option<String>,
    pub category: ErrorCategory,
    pub status_code: Option<u16>,
    pub retry_after: Option<Duration>,
}

统一的错误诊断信息

设计目标：

• 不破坏现有错误枚举与调用点
• 让上层能拿到结构化的诊断字段

字段说明

• kind: 错误大类（provider/tool/runtime/skill/memory/channel）
• message: 人类可读信息
• retriable: 是否建议重试
• source: 可选的错误来源字符串
• category: 错误详细类别
• status_code: 可选的 HTTP 状态码
• retry_after: 可选的重试等待时间

Fields

kind: String

错误类型

message: String

错误消息

retriable: bool

是否可重试

source: Option<String>

错误来源

category: ErrorCategory

错误详细类别

status_code: Option<u16>

HTTP 状态码（如果有）

retry_after: Option<Duration>

建议重试等待时间

Trait Implementations

impl Clone for ErrorDiagnostic

fn clone(&self) -> ErrorDiagnostic

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorDiagnostic

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

Formats the value using the given formatter.

impl Default for ErrorDiagnostic

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for ErrorDiagnostic

fn eq(&self, other: &ErrorDiagnostic) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
