[−][src]Struct show_notes::e019::BJustClonePoint
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);
