How to fix Rust E0382 use of moved value

Fix E0382 by cloning the value before moving it or by passing a reference instead of the value itself. Use .clone() to create a copy if you need to use the original variable again after the move.

let s1 = String::from("hello");
let s2 = s1.clone(); // Creates a new copy
// s1 is still valid here
println!("{s1}");
println!("{s2}");

Alternatively, pass a reference to avoid moving ownership:

fn takes_ownership(some_string: &String) {
    println!("{some_string}");
}

fn main() {
    let s = String::from("hello");
    takes_ownership(&s); // Pass a reference
    println!("{s}"); // s is still valid
}

The Rust E0382 use of moved value error happens because Rust moved the ownership of a value to a new location, making the original variable unusable. Think of it like handing someone a physical letter; once you give it to them, you no longer have it. To fix it, you either make a photocopy of the letter (cloning) or just let them read the original without taking it (borrowing).
