An enum is destructured similarly:
>// `allow` required to silence warnings because only
>// one variant is used.
>#[allow(dead_code)]
>enum Color {
>// These 3 are specified solely by their name.
>Red,
>Blue,
>Green,
>// These likewise tie `u32` tuples to different names: color models.
>RGB(u32, u32, u32),
>HSV(u32, u32, u32),
>HSL(u32, u32, u32),
>CMY(u32, u32, u32),
>CMYK(u32, u32, u32, u32),
>}
>fn main() {
>let color = Color::RGB(122, 17, 40);
>// TODO ^ Try different variants for `color`
>println!("What color is it?");
>// An `enum` can be destructured using a `match`.
