array-concat

Macros for concatenating const arrays.

To add to your Cargo.toml: toml array-concat = "0.3.0"

Basic Usage

concat_arrays!(<comma-seperated arrays>, <copyable value to be used for array initialization>)

Example

```rust use array_concat::*;

const A: [u32; 3] = [1, 2, 3]; const B: [u32; 2] = [4, 5]; const C: [u32; concatarrayssize!(A, B)] = concat_arrays!(A, B; u32::MIN); // compiles

// Non-Copy struct struct S {} const D: [S; 1] = [S{}]; const E: [S; 1] = [S{}]; const F: [S; concatarrayssize!(D, E)] = concat_arrays!(D, E; S{}); // doesn't compile

fn main() { let c = concatarrays!(A, B; u32::MIN); asserteq!(C[..], A.iter().chain(&B).copied().collect::>()[..]); assert_eq!(c[..], A.iter().chain(&B).copied().collect::>()[..]); } ```
