Enum ToolError 

pub enum ToolError {
    InvalidArgument {
        arg: String,
        reason: String,
    },
    ExecutionFailed(String),
    Timeout {
        timeout_ms: u64,
    },
}

Errors a tool can produce during execution.

These represent tool-level failures: bad args, network errors, timeouts. They are distinct from policy denials: a tool error means the tool was permitted but failed during execution. A policy denial means the tool was never called at all.

Variants

InvalidArgument

A required argument was missing or had an invalid value.

Fields

arg: String

reason: String

ExecutionFailed(String)

The tool ran but encountered an error during execution.

Timeout

The tool did not complete within its allowed time.

Fields

timeout_ms: u64

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.
