Represents errors that can occur during different interpolation operations.

This enum encapsulates various types of errors that might be encountered when performing numerical interpolation across different methods. Each variant corresponds to a specific interpolation technique and contains a descriptive error message.

Interpolation errors typically arise from invalid input data, mathematical constraints, or numerical stability issues specific to each interpolation method.

Variants

Linear(String)

Errors that occur during linear interpolation.

These may include insufficient data points, non-monotonic input values, or out-of-bounds interpolation attempts.

Bilinear(String)

Errors that occur during bilinear interpolation.

These may include a sample too small to build a cell from (fewer than four points on a Curve), or a checked-arithmetic step leaving the representable range.

A query in the last segments of a Curve is not one of them. The cell there is built by clamping its far edge to the curve’s last segment, which is described on BiLinearInterpolation for Curve; it used to report this error because the cell ran off the end of the sample.

Cubic(String)

Errors that occur during cubic interpolation.

These may include insufficient data points for cubic polynomial fitting, oscillation issues, or numerical instability.

Spline(String)

Errors that occur during spline interpolation.

These may include insufficient data points for spline construction, boundary condition issues, or knot placement problems.

Position(PositionError)

Error from position operations.

Curve(CurveError)

Error from curve operations.

Surface(SurfaceError)

Error from surface operations.

EmptyData

Input data set was empty so interpolation could not proceed.

OutOfRange

Requested point falls outside the valid interpolation range.

Fields

target: String

The offending coordinate (stringified for flexibility across axes).

DegenerateInterval

Interval degenerated into a point (two consecutive knots coincide).

Trait Implementations

impl Debug for InterpolationError

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

impl Display for InterpolationError

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

impl Error for InterpolationError

fn source(&self) -> Option<&(dyn Error + 'static)>

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
