Errors from math operations.

Variants

InvalidKnotVector

Knot vector length does not match control points and degree.

Fields

expected: usize

Expected number of knots.

got: usize

Actual number of knots.

InvalidWeights

Weights vector length does not match control points.

Fields

expected: usize

Expected number of weights.

got: usize

Actual number of weights.

InvalidControlPointGrid

Control point grid dimensions are inconsistent.

Fields

expected_rows: usize

Expected number of rows.

expected_cols: usize

Expected number of columns.

ZeroVector

Cannot normalize a zero-length vector.

SingularMatrix

Matrix is singular and cannot be inverted.

EmptyInput

Input collection is empty where at least one element is required.

ParameterOutOfRange

Parameter is outside the valid range.

Fields

value: f64

The out-of-range value.

min: f64

Lower bound of the valid range.

max: f64

Upper bound of the valid range.

ConvergenceFailure

Newton iteration did not converge within the allowed iterations.

Fields

iterations: usize

Number of iterations attempted.

Trait Implementations

impl Debug for MathError

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

Formats the value using the given formatter.

impl Display for MathError

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

Formats the value using the given formatter.

impl Error for MathError

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.
