[][src]Struct show_notes::e019::BJustClonePoint

pub struct BJustClonePoint {
    x: f64,
    y: f64,
    z: f64,
}

A struct which implements Clone but not Copy.

Examples

If you don't do anything, the item will be moved on assignment:

This example is not tested
let a_point = BJustClonePoint::origin();
let cloned_point = a_point;  // <- moves the value
println!("{:?}", a_point);  // <- compile error!
println!("{:?}", cloned_point);

The output is just what we would expect from the discussion on the show:

error[E0382]: use of moved value: `a_point`
--> <anon>:6:18
|
5 | let cloned_point = a_point;  // <- moves the value
|     ------------ value moved here
6 | println!("{:?}", a_point);  // <- compile error!
|                  ^^^^^^^ value used here after move
|
= note: move occurs because `a_point` has type `show_notes::e019::BJustClonePoint`, which does not implement the `Copy` trait

But you can manually call the clone method, and it will work:

let a_point = BJustClonePoint::origin();
let cloned_point = a_point.clone();
println!("{:?}", a_point);  // <- not a problem
println!("{:?}", cloned_point);
