How to fix borrow of moved value

The error occurs because you are trying to use a variable after its ownership has been moved to another location. To fix it, pass a reference to the variable instead of the variable itself by adding an ampersand (&) before the variable name in the function call and updating the function signature to accept a reference.

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

fn takes_ownership(some_string: &String) { // Accept a reference
    println!("{some_string}");
}

The borrow of moved value error means you tried to use a variable after giving it away to a function. In Rust, passing a variable usually moves its ownership, making the original variable unusable. The fix is to pass a reference (like borrowing a book from a library) so the original owner can still use it after the function finishes.
