# array-helpers

Basic length-generic operations on arrays.

This crate provides utilities for initializing, consuming, and transforming arrays.

All methods are length-generic.

This crate uses the extremely new `const_generics` feature.

As such, it requires nightly Rust.

```

let arr: [[usize; 3]; 2] = array_helpers::new(|i| array_helpers::new(|j| 3*i + j));

assert_eq!(arr, [[0,1,2],[3,4,5]]);

let arr = arr.transpose();

assert_eq!(arr, [[0,3],[1,4],[2,5]]);

let arr = arr.map(|[a,b]| (a,b));

assert_eq!(arr, [(0,3),(1,4),(2,5)]);

let (arr1, arr2) = arr.unzip();

assert_eq!(arr1, [0,1,2]);

assert_eq!(arr2, [3,4,5]);

```
