# concat_array
```rust
use concat_array::concat_array;
const A: [i32; 3] = [1, 2, 3];
const B: [i32; 4] = [4, 5, 6, 7];
const C: [i32; 2] = [8, 9];
// Example usage using function:
const AB: [i32; 7] = concat_array(A, B);
// When concatenating multiple arrays the compiler can't figure out the correct const parameters.
// Using the macro does this for you automatically.
const ABC: &[i32] = &concat_array!(A, B, C);
#[test]
fn main() {
// Can also be used in non-const contexts
let ab = concat_array(A, B);
let abc = concat_array!(A, B, C);
println!("A = {:?}", A);
println!("B = {:?}", B);
println!("C = {:?}", C);
println!();
println!("AB = {:?}", AB);
println!("ABC = {:?}", ABC);
println!();
println!("ab = {:?}", ab);
println!("abc = {:?}", abc);
assert_eq!(AB, [1, 2, 3, 4, 5, 6, 7]);
assert_eq!(ABC, [1, 2, 3, 4, 5, 6, 7, 8, 9]);
assert_eq!(AB, ab);
assert_eq!(ABC, abc);
}

## About
This project is an open-source component of [i18n.site ⋅ Internationalization Solution](https://i18n.site).
* [i18 : MarkDown Command Line Translation Tool](https://i18n.site/i18)
The translation perfectly maintains the Markdown format.
It recognizes file changes and only translates the modified files.
The translated Markdown content is editable; if you modify the original text and translate it again, manually edited translations will not be overwritten (as long as the original text has not been changed).
* [i18n.site : MarkDown Multi-language Static Site Generator](https://i18n.site/i18n.site)
Optimized for a better reading experience
## 关于
本项目为 [i18n.site ⋅ 国际化解决方案](https://i18n.site) 的开源组件。
* [i18 : MarkDown命令行翻译工具](https://i18n.site/i18)
翻译能够完美保持 Markdown 的格式。能识别文件的修改,仅翻译有变动的文件。
Markdown 翻译内容可编辑;如果你修改原文并再次机器翻译,手动修改过的翻译不会被覆盖(如果这段原文没有被修改)。
