E0382 — Use of Moved Value

Що спричиняє цю помилку

Rust's ownership system means each value has exactly one owner. When a value is moved (assigned to another variable or passed to a function), the original variable can no longer be used. This applies to types that do not implement Copy.

Як виправити

Clone the value before moving it if you need to use it again. Use references (&T or &mut T) instead of transferring ownership. Implement the Copy trait for small types. Restructure code to avoid using the value after the move.

let s = String::from("hi");
let s2 = s;
println!("{}", s);
