Struct Kernel 

pub struct Kernel { /* private fields */ }

The tap bank at one lattice ratio, for a source at a rate of its own.

The taps are the measured ones where the ratio is the measured ratio, whatever pair of rates spells it, and the same shape at that ratio’s own [cutoff] otherwise. Build one per resampling run: a derived bank is computed on construction, not per field.

Implementations

impl Kernel

pub fn new(num: u32, den: u32) -> Kernel

The kernel for a lattice of num source samples per den fields — a source rate and a target rate, in that order, or any ratio equal to theirs.

pub fn accumulate(&self, source: &[i16], field: usize) -> f64

Sum field f’s tap products in f64; samples outside source are zero.

pub fn field(&self, source: &[i16], at: usize) -> i64

Return a field in source units, truncating toward zero once after the full sum.
