Enums are a fundamental feature in Rust that let you define a type that can be one of several distinct variants. Enums make it easier to represent a set of related states or options cleanly and effectively.
In this challenge, you will implement a simple TrafficLight enum to represent the states of a traffic light: Red, Yellow, and Green. Each variant will be a unit struct with no associated data.
Create an enum TrafficLight with three variants:
Red representing the red light.Yellow representing the yellow light.Green representing the green light.Write a function light_action that takes a TrafficLight and returns a string describing the action associated with the light.
Red, return "Stop".Yellow, return "Caution".Green, return "Go".match statement to handle each enum variant.
