Suppose I have the enum :
enum Coll<T> {
A(f64,T),
B(f64,T)
}
I know that the compiler can automatically derive the Clone trait for the
above. However I would like to manually implement it and was unsuccessful
in my attempt. I tried the following :
enum Coll<T> {
A(f64,T),
B(f64,T)
}
impl<T: Clone> Clone for Coll<T> {
fn clone (&self) -> Coll<T> {
match *self {
A(x,y) => A(x,y.clone()),
B(x,y) => B(x,y.clone())
}
}
}
but I got the error message :
q.rs:9:13: 9:19 error: cannot move out of dereference of `&`-pointer
q.rs:9 A(x,y) => A(x,y.clone()),
^~~~~~
q.rs:10:13: 10:19 error: cannot move out of dereference of `&`-pointer
q.rs:10 B(x,y) => B(x,y.clone())
^~~~~~
error: aborting due to 2 previous errors
What do I need to do to fix the code above? Thanks
