Trait Interpolator

pub trait Interpolator<IndexType, ValueType>
where
    IndexType: InterpolationIndex,
    ValueType: InterpolationValue,
{
    // Required methods
    fn fit(&mut self) -> Result<(), RustQuantError>;
    fn interpolate(&self, point: IndexType) -> Result<ValueType, RustQuantError>;
    fn range(&self) -> (IndexType, IndexType);
    fn add_point(&mut self, point: (IndexType, ValueType));
}

Interpolator trait. This trait is implemented by all interpolation models.

Required Methods

fn fit(&mut self) -> Result<(), RustQuantError>

Fit the interpolator to the data.

Errors

• RustQuantError::UnequalLength when the length of xs != ys.

fn interpolate(&self, point: IndexType) -> Result<ValueType, RustQuantError>

Interpolate at value point.

Errors

• RustQuantError::Unfitted when the interpolator has not been fitted.

fn range(&self) -> (IndexType, IndexType)

Return range of interpolation.

fn add_point(&mut self, point: (IndexType, ValueType))

Add a point to the interpolator.
