What is the difference between Copy and Clone traits in Rust?

I just started learning Rust and got confused about two traits — Copy and Clone. They both seem to allow copying values, but the compiler behaves differently. Here's an example that confused me. I'm trying to copy a struct: ```rust struct Point { x: i32, y: i32, } fn main() { let p1 = Point { x: 10, y: 20 }; let p2 = p1; // move let p3 = p1; // error: use of moved value } ``` If I add `#[derive(Copy)]`, the code works: ```rust #[derive(Copy, Clone)] struct Point { x: i32, y: i32, } ``` But if I only use `Clone`, I have to explicitly call `.clone()`: ```rust let p2 = p1.clone(); ``` Why is that? When should I use Copy and when Clone? What is the fundamental difference? And why does Copy require Clone (I've seen that
