Struct CtlError 

pub struct CtlError {
    pub code: ErrorCode,
    pub message: String,
    pub evidence: Option<Value>,
}

统一错误类型(ADR-004):单一枚举,code() 映射与恢复建议的唯一处。 变体随命令实现扩充;运行路径禁止裸 unwrap/expect。

Fields

code: ErrorCode

message: String

evidence: Option<Value>

结构化证据(如 AMBIGUOUS 的候选列表,docs/12 §4 协议评审项): agent 可免重取 snapshot 直接裁决。

Implementations

impl CtlError

pub fn new(code: ErrorCode, message: impl Into<String>) -> Self

pub fn with_evidence( code: ErrorCode, message: impl Into<String>, evidence: Value, ) -> Self

pub fn protocol(message: impl Into<String>) -> Self

pub fn internal(message: impl Into<String>) -> Self

Trait Implementations

impl Debug for CtlError

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

Formats the value using the given formatter.

impl Display for CtlError

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

Formats the value using the given formatter.

impl Error for CtlError

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.
