Invalid native scalar constraint or transform input.

Variants

NonFiniteCoefficient

A coefficient, offset, or fixed value is non-finite.

TargetIsSource

A target is also used directly as its source.

Fields

target: ParameterKey

Invalid target.

EmptyLinearTerms

A linear constraint has no sources.

DuplicateLinearSource

A linear constraint repeats one source.

Fields

source: ParameterKey

Repeated source.

UnknownTarget

A target does not belong to the parameter set.

Fields

target: ParameterKey

Missing target.

DuplicateTarget

More than one constraint owns a target.

Fields

target: ParameterKey

Repeated target.

UnknownSource

A source does not belong to the parameter set.

Fields

source: ParameterKey

Missing source.

UnresolvedDependency

A source is constrained later or belongs to a dependency cycle.

Fields

target: Box<ParameterKey>

Target currently being resolved.

source: Box<ParameterKey>

Unavailable source.

MissingValue

A caller-supplied value map omits a free key.

Fields

key: ParameterKey

Missing key.

VectorLengthMismatch

A solver vector has the wrong length.

Fields

expected: usize

Required length.

actual: usize

Received length.

NonFiniteVector

A packed or unpacked solver value is non-finite.

MatrixSizeOverflow

Derivative matrix dimensions overflow the platform element count.

InternalInvariant

Private validated transform state is unexpectedly inconsistent.

ExpandedValueOutsideBounds

One expanded physical value violates its declared bounds.

Fields

key: ParameterKey

Invalid parameter.

value: f64

Expanded value.

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
