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.

```rust use arrcat::concat_arrays;

{ const PRIMES: [u16; 4] = [7, 11, 13, 17]; asserteq!( concatarrays!([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]);

}

```

No-std support

arrcat is #![no_std], it can be used anywhere Rust can be used.

Minimum Supported Rust Version

arrcat requires Rust 1.57.0, requiring crate features to use newer language features.
