Struct ConstraintError 

pub struct ConstraintError { /* private fields */ }

Error type for proposer constraint violations (DEF-PS-15).

Tracks which constraint clauses failed: ontology-bounded or operator-reachable. Used for audit logging (OBL-PS-04) and debugging.

Implementations

impl ConstraintError

pub fn new( ontology_bounded_failed: bool, operator_reachable_failed: bool, details: impl Into<String>, ) -> Self

Create a new constraint error with details.

pub fn ontology_bounded_failed(&self) -> bool

Did the candidate fail the ontology-bounded constraint?

pub fn operator_reachable_failed(&self) -> bool

Did the candidate fail the operator-reachable constraint?

pub fn details(&self) -> &str

Human-readable details of the failure.

Trait Implementations

impl Clone for ConstraintError

fn clone(&self) -> ConstraintError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConstraintError

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

Formats the value using the given formatter.

impl Display for ConstraintError

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

Formats the value using the given formatter.

impl Error for ConstraintError

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.
