Failure while validating or applying a model construction contract.

Variants

UnregisteredVariant

No concrete variant matches the requested problem reference.

Fields

name: String

Canonical problem name.

variant: BTreeMap<String, String>

Exact requested variant.

ExpectedObject

Construction values must be supplied as a named JSON object.

DuplicateInput(String)

A construction contract declared the same input more than once.

UnknownInputs(Vec<String>)

The caller supplied values outside the declared construction contract.

MissingInputs(Vec<String>)

The caller omitted required construction values.

InvalidInput(String)

Normalized values could not be deserialized into the direct model or create spec.

Conversion(String)

A typed create spec failed to convert into the problem model.

IntegerOverflow(String)

Arithmetic used to produce a stored model field overflowed.

NonFiniteFloat(String)

A stored approximate value is not finite.

InexactFloatConversion(ExactI64ToF64Error)

An exact integer cannot be stored in the target floating-point domain.

Trait Implementations

impl Clone for ConstructionError

fn clone(&self) -> ConstructionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConstructionError

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

Formats the value using the given formatter.

impl Display for ConstructionError

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

Formats the value using the given formatter.

impl Eq for ConstructionError

impl Error for ConstructionError

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<&str> for ConstructionError

fn from(message: &str) -> Self

Converts to this type from the input type.

impl From<ExactI64ToF64Error> for ConstructionError

fn from(source: ExactI64ToF64Error) -> Self

Converts to this type from the input type.

impl From<Infallible> for ConstructionError

fn from(value: Infallible) -> Self

Converts to this type from the input type.

impl From<String> for ConstructionError

fn from(message: String) -> Self

Converts to this type from the input type.

impl PartialEq for ConstructionError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
