Function lattice_qcd_rs::statistics::mean_par_iter_val

pub fn mean_par_iter_val<It, T>(data: It) -> Twhere
    T: Clone + Div<f64, Output = T> + Sum<T> + Sum<It::Item> + Send,
    It: IndexedParallelIterator<Item = T>,

Compute the mean from a [rayon::iter::IndexedParallelIterator]. If you want to use reference use mean_par_iter. It uses the power of the parallel iterator to do the computation and is particularly useful in combination of a map.

Example

use lattice_qcd_rs::statistics::mean_par_iter_val;
use rayon::prelude::*;

fn expensive_computation(input: &f64) -> f64 {
    input + 1_f64
}

let vec = vec![1_f64, 2_f64, 3_f64, 4_f64];
let mean = mean_par_iter_val(vec.par_iter().map(|input| expensive_computation(input)));
