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