}

Validation errors for solver inputs.

These are raised eagerly before any computation begins so that callers get clear diagnostics rather than mysterious numerical failures.

Variants

DimensionMismatch(String)

Matrix dimensions are inconsistent (e.g. row_ptrs length vs rows).

NonFiniteValue(String)

A value is NaN or infinite where a finite number is required.

IndexOutOfBounds

A column index is out of bounds for the declared number of columns.

Fields

index: u32

Offending column index.

row: usize

Row containing the offending entry.

cols: usize

Declared column count.

NonMonotonicRowPtrs

The row_ptrs array is not monotonically non-decreasing.

Fields

position: usize

Position in row_ptrs where the violation was detected.

ParameterOutOfRange

A parameter is outside its valid range.

Fields

name: String

Name of the parameter.

value: String

The invalid value (as a string for flexibility).

expected: String

Human-readable description of the valid range.

MatrixTooLarge

Matrix size exceeds the implementation limit.

Fields

rows: usize

Number of rows.

cols: usize

Number of columns.

max_dim: usize

Maximum supported dimension.

Trait Implementations

impl Debug for ValidationError

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

Formats the value using the given formatter.

impl Display for ValidationError

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

Formats the value using the given formatter.

impl Error for ValidationError

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<ValidationError> for SolverError

fn from(source: ValidationError) -> Self

Converts to this type from the input type.
