Why is my implicitly copied variable moving around?

Question

According to the Rust link at the time of this writing:

For types that contain ownership pointers or values ​​that implement the special Drop attribute, the variable moves. All other types are copied.

Below is my code. I expect it to Pointbe a copy type. But it moves, and the following code will not compile with 0.13.0 at night.

struct Point {
    x: uint,
    y: uint
}

fn main() {
    let p: Point = Point{x: 10u, y: 10u};

    let p1 = p;
    let p2 = p; //Error: p has been moved p1
}

Compilation Error:

note: `p` moved here because it has type `Point`, which is moved by default

Why is it Pointnot considered as a type for copying?

Answer 1

Copy should now be added explicitly, the manual just hasn't been updated:

#[derive(Copy)]
struct Point {
    x: uint,
    y: uint
}

fn main() {
    let p: Point = Point{x: 10u, y: 10u};

    let p1 = p;
    let p2 = p; // Now works because it is Copy.
}
