par-array-init

The par-array-init crate allows you to initialize arrays with an initializer closure that will be called in parallel to fill the array.

This crate mirrors the api of crate (array-init)[https://crates.io/crates/array-init] with the caveat that initialization is performed in parallel. An important departure from array-init, initialization order is not deterministic and should not be relied on.

Parallelization is achieved using (rayon)[https://https://crates.io/crates/rayon] and it's ParallelIterator api.

Examples:

# extern crate par_array_init;
# extern crate rayon;

// Initialize an array of length 10 containing successive squares

let arr: [usize; 50] = par_array_init::par_array_init(|i| i * i);

// Initialize an array from an iterator producing an array of 34 repeated

let mut iter = rayon::iter::repeat(34u32);
let arr: [u32; 50] = par_array_init::from_iter(iter);
