array_ext

Extra functionality for Rust arrays.

Examples

The trait Array provides fixed-size array generics:

use array_ext::Array;

fn average<T: Array<f32>>(arr: T) -> f32
{
    let n = arr.len() as f32;
    arr.foldl(0.0, |acc, val| acc + val) / n
}

assert!((average([8.96, 3.14, 17.9]) - 10.0).abs() < f32::EPSILON);

Currently implemented for array sizes from 0 to 32, hardcoded as workaround for the lack of integer generics.

The map and zip methods are provided by the sized Array1, Array2, ... types. The base Array type only provides a map_ method that can do T -> T mapping.
