Enums in RUST

 Enums in RUST

Enums allow you to define a type by enumerating its possible variants. They can be used to represent things like states or options. Here's an example:

rust

enum TrafficLight {

    Red,

    Yellow,

    Green,

}

fn main() {

    let red = TrafficLight::Red;

    let yellow = TrafficLight::Yellow;

    let green = TrafficLight::Green;

}
