Enum ExtrapolationBehavior 

pub enum ExtrapolationBehavior {
    Nearest,
    Linear,
    Polynomial(usize),
    Reflection,
    Periodic,
}

Extrapolation behaviour for queries outside [x_min, x_max].

This enum is deliberately kept simple and orthogonal. For the richer physics-informed and ensemble strategies, see crate::extrapolation.

Variants

Nearest

Clamp x to the nearest boundary value.

Linear

Linearly extrapolate using the finite-difference slope at the boundary.

Step size h = (x_max - x_min) * 1e-6.

Polynomial(usize)

Neville polynomial extrapolation of the given degree.

Uses degree + 1 equally-spaced interior points near the boundary. The degree is clamped to 9 (10-point stencil) to avoid blow-up.

Reflection

Mirror x about the boundary, then evaluate the interior function.

Periodic

Wrap x with period x_max - x_min, then evaluate the interior function.

Trait Implementations

impl Clone for ExtrapolationBehavior

fn clone(&self) -> ExtrapolationBehavior

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExtrapolationBehavior

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

Formats the value using the given formatter.

impl PartialEq for ExtrapolationBehavior

fn eq(&self, other: &ExtrapolationBehavior) -> 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.
