[][src]Struct show_notes::e019::ANoCopyOrClonePoint

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

A non-copyable point type

Examples

This example is not tested
let a_point = ANoCopyOrClonePoint::origin();
let moved_point = a_point;  // <- moves the value
println!("{:?}", a_point);  // <- so this is a problem!
println!("{:?}", moved_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 moved_point = a_point;  // <- moves the value
|     ----------- value moved here
6 | println!("{:?}", a_point);  // <- so this is a problem!
|                  ^^^^^^^ value used here after move
|
= note: move occurs because `a_point` has type `show_notes::e019::ANoCopyOrClonePoint`, which does not implement the `Copy` trait

If we comment the offending line out, however, it compiles just fine.

let a_point = ANoCopyOrClonePoint::origin();
let moved_point = a_point;
// println!("{:?}", a_point);
println!("{:?}", moved_point);  // <- not a problem!

(You can confirm this in the playground.)
