Enum EvaluatorError 

pub enum EvaluatorError {
    UnsupportedPlatform {
        reason: String,
    },
    SandboxLimitExceeded {
        limit: String,
    },
    Execution {
        reason: String,
    },
}

Structured errors surfaced by concrete evaluators in this module tree (T080–T082).

Evaluators fold these into EvalMetricResult via Score::fail() with the error message copied into details; the type exists primarily so callers (tests, reporters) can reason about the failure mode programmatically.

Variants

UnsupportedPlatform

The current platform cannot run this evaluator (e.g. Windows sandbox).

Fields

reason: String

Free-form explanation of the missing platform capability.

SandboxLimitExceeded

A sandbox resource-limit cap was exceeded at evaluation time (T081).

Fields

limit: String

Name of the exceeded limit (wall_clock, cpu, memory, fds, network).

Execution

The evaluator could not carry out a deterministic operation.

Fields

reason: String

Human-readable explanation of the failure.

Implementations

impl EvaluatorError

pub fn into_metric_details(self) -> String

Convenience: render the error as the details string paired with Score::fail().

Trait Implementations

impl Debug for EvaluatorError

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

Formats the value using the given formatter.

impl Display for EvaluatorError

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

Formats the value using the given formatter.

impl Error for EvaluatorError

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.
