Enum ToolError 

pub enum ToolError {
    InvalidInput(String),
    ExecutionFailed(String),
    Timeout(u64),
    ToolNotFound(String),
    McpError {
        code: i32,
        message: String,
        data: Option<Value>,
    },
}

Tool error type.

Variants

InvalidInput(String)

Input validation error.

ExecutionFailed(String)

Timeout(u64)

Timeout.

ToolNotFound(String)

Tool not found.

McpError

MCP 传输层错误(经 MCPToolAdapter 适配),保留 code/message/data(P1-6)。

不静默降级为 ExecutionFailed,上层可据 code 区分连接断开 / 方法不存在 / 参数错误等场景。

Fields

code: i32

message: String

data: Option<Value>

Trait Implementations

impl Debug for ToolError

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

Formats the value using the given formatter.

impl Display for ToolError

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

Formats the value using the given formatter.

impl Error for ToolError

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<ToolError> for CoreError

fn from(source: ToolError) -> Self

Converts to this type from the input type.
