Enum EvalRunError 

pub enum EvalRunError {
    Run {
        index: usize,
        source: RunError,
    },
    CaseOutOfRange {
        requested: usize,
        suite_size: usize,
    },
}

Why scoring an eval suite failed.

Either a case’s submission could not be run through the pipeline — the interpreter failed to launch or the provider call failed — or a --case N selection was out of range. A scoring run is all-or-nothing, since a missing verdict cannot be scored as either polarity; the run failure names the offending case so an instructor can find it.

Variants

Run

A case’s submission failed to run through the pipeline.

Fields

index: usize

The zero-based index of the case whose run failed, in suite order.

source: RunError

The underlying pipeline failure.

CaseOutOfRange

A --case N selection named a case outside the suite.

Carries the user’s requested number and the suite size; the CLI maps this to exit 1 with a stderr message naming suite_size.

Fields

requested: usize

The user’s requested case number (1-based).

suite_size: usize

The number of cases in the suite.

Trait Implementations

impl Debug for EvalRunError

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

Formats the value using the given formatter.

impl Display for EvalRunError

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

Formats the value using the given formatter.

impl Error for EvalRunError

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>)
