Methods

impl InterpAccel

fn new() -> InterpAccel

This function returns a pointer to an accelerator object, which is a kind of iterator for interpolation lookups. It tracks the state of lookups, thus allowing for application of various acceleration strategies.

fn reset(&mut self)

This function reinitializes the accelerator object acc. It should be used when the cached information is no longer applicable—for example, when switching to a new dataset.

fn find(&mut self, x_array: &[f64], x: f64) -> usize

This function performs a lookup action on the data array x_array of size size, using the given accelerator a. This is how lookups are performed during evaluation of an interpolation. The function returns an index i such that x_array[i] <= x < x_array[i+1].

Trait Implementations

impl Copy for InterpAccel

impl Clone for InterpAccel

fn clone(&self) -> InterpAccel

Returns a copy of the value.

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

Performs copy-assignment from source.
