Today's code
ownership.rs
fn main() {
let s1 = String::from("namara");
let s2 = s1;
println!("{}", s1);
}
Does this compile? If not, why?
Answer
No. String doesn't implement Copy, so let s2 = s1; moves ownership out of s1. Using s1 again on the next line is a use of a moved value, and the compiler rejects it: error[E0382]: borrow of moved value: `s1`.
