cartesian-array-product

This crate provides a macro to generate an array with the cartesian product of multiple arrays.

It is meant to be usable in const contexts.

Usage

Add this crate as a dependency:

bash cargo add cartesian_array_product

Example

```rust use cartesianarrayproduct::cartesian_array;

let product = cartesian_array!([1, 2], [3, 4]); let expected = [ (1, 3), (2, 3), (1, 4), (2, 4), ];

assert_eq!(product, expected); ```

See https://docs.rs/cartesian_array_product for further info.

Caveat

This macro doesn't allow trailing commas in the input arrays. This is because $($var:whatever),* doesn't match trailing commas, and adding manually $($var:whatever),* $(,)? is too much repetation for a thing that, honestly, isn't that important. (maybe i'm just writing this to convience myself because i hate not having trailing commas 😭😭😭)
