Enum EvaluationError 

pub enum EvaluationError {
    InvalidSubject(&'static str),
    InvalidCriteria,
    CriterionMismatch,
    FindingMismatch,
    SubjectMismatch,
    IllegalTransition,
    VerdictMismatch,
}

Errors raised while constructing or advancing the evaluation contract.

Variants

InvalidSubject(&'static str)

Mission/Goal roles or another subject invariant is invalid.

InvalidCriteria

Criteria are empty, duplicated or malformed.

CriterionMismatch

A report does not exactly match the claim’s criterion set.

FindingMismatch

A report finding is duplicated, unknown or malformed.

SubjectMismatch

A report was produced for a different subject revision.

IllegalTransition

An operation is not legal from the current lifecycle state.

VerdictMismatch

A report’s caller-provided aggregate verdict disagrees with its criterion results.

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 Eq for EvaluationError

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 PartialEq for EvaluationError

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

Equality operator ==.

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

Inequality operator !=.
