Error E0382

Error E0382 occurs because you are trying to use a variable after its ownership has been moved to another variable. To fix this, either clone the value if it implements the Clone trait, or pass a reference (&) instead of the value itself.

let s1 = String::from("hello");
let s2 = s1.clone(); // Creates a deep copy
println!("{} and {}", s1, s2);

Alternatively, borrow the value:

let s1 = String::from("hello");
let s2 = &s1; // Borrows s1
println!("{} and {}", s1, s2);

Error E0382: "use of moved value" happens because Rust prevents you from using data after you have given it away to another variable. Think of it like handing someone a physical letter; once you give it to them, you no longer have it to read. To fix it, you must either make a photocopy of the letter (clone) or just let them look at it without taking it (borrow).
