Enum Error 

pub enum Error {
    NotFound {
        resource: Resource,
        id: ResourceId,
    },
    PolicyDenied {
        reason: Reason,
    },
    External {
        failure: ExternalFailure,
    },
}

Decision choices for error in the agent tool error surface; each value guides source-grounded routing and review.

Variants

NotFound

Resource copied from reviewed source input for audit, reviewer explanation, or agent context; callers must not invent or mutate it.

Fields

resource: Resource

Resource value stored on this variant.

id: ResourceId

Id value stored on this variant.

PolicyDenied

Reason copied from reviewed source input for audit, reviewer explanation, or agent context; callers must not invent or mutate it.

Fields

reason: Reason

Reason value stored on this variant.

External

Failure copied from reviewed source input for audit, reviewer explanation, or agent context; callers must not invent or mutate it.

Fields

failure: ExternalFailure

Failure value stored on this variant.

Implementations

impl Error

pub fn policy_denied(reason: Reason) -> Self

Builds policy denied for the agent tool error gate rules from validated source facts while preserving review gates and draft-only side effects.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 PartialEq for Error

fn eq(&self, other: &Error) -> 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.
