error[E0382]: borrow of moved value

Rust ownership: the value was moved and cannot be reused. - Clone it: `let y = x.clone();` - Borrow instead of moving: `fn f(x: &T)` - Use a reference-counted wrapper (`Rc` / `Arc`) if shared ownership is needed. Reference: https://doc.rust-lang.org/book/ch04-02-references-and-borrowing.html
