A small collection of traits for implementing higher order functions.

Init:

```rust use higherorderfunctions::Init;

struct House { number: usize }

// [T; N]: Init let road = <[House; 3]>::init(|i| House { number: i + 1 });

asserteq!(road[0].number, 1); asserteq!(road[1].number, 2); assert_eq!(road[2].number, 3); ```

Map:

```rust use higherorderfunctions::Map;

let arr = [1, 4, 6, -3, 6].map(|x| x * 2);

assert_eq!(arr, [2, 8, 12, -6, 12]); ```

```rust use higherorderfunctions::Map;

let arr = [1, 4, 6, -3, 6].map(f64::from);

assert_eq!(arr, [1.0, 4.0, 6.0, -3.0, 6.0]); ```

To use this, add it as a dependency to your Cargo.toml: toml [dependencies] higher_order_functions = "0.1.0"
