"cannot move out of borrowed content" — How to Fix

Fix 'cannot move out of borrowed content' by passing ownership directly or cloning the value before use.

The error occurs because you are trying to move a value out of a reference, which is forbidden in Rust. To fix this, change the function parameter to take ownership of the value instead of borrowing it, or clone the value if you need to keep the original.

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

fn main() {
    let s = String::from("hello");
    takes_ownership(s); // s is moved here
}

If you must keep the original value, clone it before passing it:

fn main() {
    let s = String::from("hello");
    takes_ownership(s.clone()); // s is cloned, original remains valid
}
