How to concatenate multiple arrays with a fixed size in Rust

Answer 1

use std::vec::Vec;

fn main() {
    let arr1 = [7, 3, 2, 9, 1];
    let arr2 = [5, 8, 6, 4, 0];
    let arr3 = [9, 34, 90, 0, 100, 3];

    let merged: Vec<_> = [arr1, arr2, arr3].concat();

    println!("{:?}", merged);
}


    
/*
run:

[7, 3, 2, 9, 1, 5, 8, 6, 4, 0, 9, 34, 90, 0, 100]
  
*/
