Cargo feature array (enabled by default). To compile only this module:

cargo add helpers4 --no-default-features --features array

or in Cargo.toml:

pub fn cartesian_product<A: Clone, B: Clone>(a: &[A], b: &[B]) -> Vec<(A, B)>

Parameter	Type	Description
`a`	`&[A]`	The first slice.
`b`	`&[B]`	The second slice.

Vec<(A, B)>

use helpers4::array::cartesian_product;

    cartesian_product(&[1, 2], &['a', 'b']),
    vec![(1, 'a'), (1, 'b'), (2, 'a'), (2, 'b')]
