Me gustaría tomar un segmento mutable y copiar el contenido en dos nuevos segmentos mutables. Cada rebanada es la mitad del original.

Mi intento # 1:

let my_list: &mut [u8] = &mut [0, 1, 2, 3, 4, 5];
let list_a: &mut [u8] = my_list[0..3].clone();
let list_b: &mut [u8] = my_list[3..6].clone();
println!("{:?}", my_list);
println!("{:?}", list_a);
println!("{:?}", list_b);

Salida:

error: no method named `clone` found for type `[u8]` in the current scope
 --> src/main.rs:3:43
  |
3 |     let list_a: &mut [u8] = my_list[0..3].clone();
  |                                           ^^^^^

  |                                           ^^^^^

Mi intento # 2:

let my_list: &mut [u8] = &mut [0, 1, 2, 3, 4, 5];
let list_a: &mut [u8] = my_list[0..3].to_owned();
let list_b: &mut [u8] = my_list[3..6].to_owned();
println!("{:?}", my_list);
println!("{:?}", list_a);
println!("{:?}", list_b);

<, p> puedo usar dosVec<u8> y supongo que solo debo recorrer la entrada y presionar valores clonados, pero esperaba que hubiera una mejor manera de hacer esto:

extern crate rand;

use rand::{thread_rng, Rng};

fn main() {
    let my_list: &mut [u8] = &mut [0; 100];
    thread_rng().fill_bytes(my_list);
    let list_a = &mut Vec::new();
    let list_b = &mut Vec::new();
    for i in 0..my_list.len() {
        if i < my_list.len() / 2 {
            list_a.push(my_list[i].clone());
        } else {
            list_b.push(my_list[i].clone());
        }
    }
    println!("{:?}", list_a.as_slice());
    println!("{:?}", list_b.as_slice());
    println!("{:?}", my_list);
}
