Derive Macro enum_cycling_derive::EnumCycle

#[derive(EnumCycle)]
{
    // Attributes available to this derive:
    #[skip]
    #[cycle]
}

auto-derives EnumCycle for the enum. Each variant of the enum will move to the one above / below itself. Variants of the enum can be skipped using #[skip].

When a variant moves to one that can contain a value, the default value for that type will be used for the values of the returned enum variant.

Calling up / down on a variant that was skipped will result in a panic.
