A very simple question - returning a non-Copy structure from function

help

Oh really? If so how to fix the build error of this program:

#[derive(Debug)]
struct SA {
    x: i32,
    s: Vec<u8>,
}

fn fg() -> SA {
    let mut a = SA {
        x: 1,
        s: Vec::new(),
    };
    a.s.push(0);
    a.s.push(1);
    a
}

fn main() {
    let b = fg();
    println!("b is: {:?}", b);
    
    let c = [fg(); 10];
}

the build error says:

Compiling playground v0.0.1 (file:///playground)
error[E0277]: the trait bound `SA: std::marker::Copy` is not satisfied
  --> src/main.rs:21:13
   |
21 |     let c = [fg(); 10];
   |             ^^^^^^^^^^ the trait `std::marker::Copy` is not implemented for `SA`
   |
   = note: the `Copy` trait is required because the repeated element will be copied

error: aborting due to previous error
