Enum ExtrapolationMode 

pub enum ExtrapolationMode {
    Nearest,
    Linear,
    Polynomial(usize),
    Reflect,
    Periodic,
    Fill(f64),
    Error,
}

How to handle queries outside the interpolation domain [x_min, x_max].

Variants

Nearest

Clamp x to the nearest boundary and evaluate the interpolant there.

Linear

Linear extrapolation using a finite-difference gradient at the boundary.

The gradient is estimated with step h (defaults to (x_max - x_min) * 1e-5).

Polynomial(usize)

Polynomial extrapolation of degree deg using deg+1 equally-spaced points near the boundary.

Reflect

Reflect x about the boundary and evaluate at the reflected point.

For a lower boundary at x_min: reflected point is 2 x_min - x. For an upper boundary at x_max: reflected point is 2 x_max - x.

Periodic

Wrap x periodically so the period equals x_max - x_min.

Fill(f64)

Return v for every out-of-domain query.

Error

Return InterpolateError::OutOfBounds for out-of-domain queries.

Trait Implementations

impl Clone for ExtrapolationMode

fn clone(&self) -> ExtrapolationMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExtrapolationMode

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

Formats the value using the given formatter.

impl PartialEq for ExtrapolationMode

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