Trait orx_funvec::FromIndex

pub trait FromIndex<const DIM: usize> {
    // Required method
    fn from_index(index: [usize; DIM]) -> Self;
}

A convenience trait to allow extending FunVec implementations.

A struct implementing FromIndex<DIM> can be created from [usize; DIM], such as:

• usize, (usize), [usize; 1] implement FromIndex<1>, and hence, can be created from [usize; 1];
• (usize, usize), [usize; 2] implement FromIndex<2>, and hence, can be created from [usize; 2];
• …

Required Methods

fn from_index(index: [usize; DIM]) -> Self

Converts the index [usize; DIM] into value.

Example

use orx_funvec::*;

let index = [2];
let i = usize::from_index(index);
assert_eq!(i, 2);

let index = [3, 4];
let (i, j) = <(usize, usize)>::from_index(index);
assert_eq!(i, 3);
assert_eq!(j, 4);
