Array concatenation

This crate allows concatenating multiple arrays of varying lengths into one array.

Example

concat_arrays

For more examples of using concat_arrays, you can look here.

use arrcat::concat_arrays;

{
    const PRIMES: [u16; 4] = [7, 11, 13, 17];
    assert_eq!(
        concat_arrays!([3, 4, 4u16.pow(3)], PRIMES),
        [3, 4, 64, 7, 11, 13, 17],
    );
}

{

    let increasing = [8, 9, 10];

    let concated = concat_arrays!(
        // the macro can't infer the length of runtime array non-literals.
        increasing: [_; 3],
        // most non-literal arguments need to be wrapped in `()` or `{}`.
        ([2u16, 3, 4].map(|x| x * 9)): [_; 3],
    );

    assert_eq!(concated, [8, 9, 10, 18, 27, 36]);
}
