Struct Cache 

pub struct Cache<T> { /* private fields */ }

Cache holding values retrieved from the za array.

This object caches the values extracted from the za array, which are more likely to be used again, either by evaluating the spline to a nearby point, or/and by evaluating it’s derivates as well.

Only the grid points are cached, not any interpolated values.

This optimization seems to be quite effective (up to +50% from my testing), and could be important in cases where za arrays are big and don’t fit in the CPU’s cache. It is of course, very situational, since it also depends on the way one evaluates his splines.

The overhead of cache misses should be truly negligible, since the process just falls back to calculating the values in the usual manner.

Implementations

impl<T> Cache<T>

where T: Num,

pub fn new() -> Self

Creates a new empty [Cache2d]

pub fn reset(&mut self)

pub fn soft_reset(&mut self)

Resets the indices. Useful for benchmarking, to avoid the overhead of resetting all the fields at each iteration.
