Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

EmptyField

A required name or version was empty.

Fields

field: &'static str

Invalid field name.

EmptyDataset

A dataset contains no cases.

EmptyRules

A rule scorer contains no rules.

InconsistentReport

A serialized report contradicts its per-case evidence.

Fields

message: &'static str

Stable inconsistency explanation.

NoScorers

A runner without scorers cannot measure quality.

DuplicateCase

A case identifier occurs more than once.

Fields

case_id: String

Duplicated case identifier.

DuplicateScorer

A scorer name occurs more than once.

Fields

scorer: String

Duplicated scorer name.

InvalidRatio

A score or threshold is not finite and within zero through one.

Fields

field: &'static str

Invalid field name.

value: f64

Rejected value.

InvalidMetric

A duration or monetary metric was negative or non-finite.

Fields

field: &'static str

Invalid field name.

value: f64

Rejected value.

Target

The evaluated target failed to produce an output.

Fields

message: String

Safe failure explanation.

Scorer

A scorer could not evaluate one output.

Fields

scorer: String

Stable scorer name.

message: String

Safe failure explanation.

DatasetMismatch

Reports from different dataset identities cannot be compared.

Fields

baseline_name: String

Baseline dataset name.

baseline_version: String

Baseline dataset version.

candidate_name: String

Candidate dataset name.

candidate_version: String

Candidate dataset version.

Trait Implementations

impl Clone for EvaluationError

fn clone(&self) -> EvaluationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EvaluationError

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

Formats the value using the given formatter.

impl Display for EvaluationError

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

Formats the value using the given formatter.

impl Error for EvaluationError

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<EvaluationError> for EvaluationStoreError

fn from(source: EvaluationError) -> Self

Converts to this type from the input type.

impl PartialEq for EvaluationError

fn eq(&self, other: &EvaluationError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
