The “trait Clone is is not implemented” when deriving the trait Copy for Enum

Question

The following code:

#[derive(Copy)]
enum MyEnum {
    Test
}

Is giving me this error: error: the trait core::clone::Clone is not i

Answer 1

This happens because the trait Copy, depends on the trait Clone. The compiler will not try to infer and implement the trait for you. So you must explicitly implement the Clone trait as well.

Like that:

#[derive(Copy,Clone)]
enum MyEnum {
  Test
}
