Print complete enum

Hi,

I would like to print all variants of an enum. So e.g. for

enum Foo {
    Abc,
    Xyz,
}

I would like to see something like "Abc/Xyz".

I implemented Display for Foo like this ...

impl Display for Foo {
     fn fmt(&self, f: &mut Formatter<'_>) -> fmt::Result {
         write!(f, "{:?}/{:?}", Foo::Abc, Foo::Xyz)
     }
}

and then could do it with println!("{}", Foo::Abc) but using a variant to print the whole enum feels wrong.

Then I tried to use Action::iter() from the strum crate but could not figure out how to use it properly.

Any idea how this could be done?

Thanks.
