Rust program to demonstrate the Match Statement with Enum (Enum Example)

Rust | Enum Example: Write a program to demonstrate the Match Statement with Enum.
Submitted by Nidhi, on October 28, 2021

Problem Solution:

In this program, we will create an enum Color. Then we will use enum constants with the Match statement.

Program/Source Code:

The source code to demonstrate the Match Statement with Enum is given below. The given program is compiled and executed successfully.

// Rust program to demonstrate the 
// Match Statement with Enum

#[derive(Debug)]

enum Color {
   RED,GREEN,YELLOW
}

fn Fun(color:Color) {
   match color {
      Color::RED => {
         println!("Color is RED");
      },
      Color::GREEN => {
         println!("Color is GREEN");
      },
      Color::YELLOW =>{
         println!("Color is YELLOW");
      }
   }
}

fn main() {
   Fun(Color::RED);
   Fun(Color::GREEN);
   Fun(Color::YELLOW);
}

Output:

Color is RED
Color is GREEN
Color is YELLOW

Explanation:

In the above program, we created an enum Color and functions Fun(), main(). The enum Color contains constants RED, GREEN, and YELLOW.

The Fun() function accepts the enum as a parameter and here we used enum with match statement. In the main() function, we called the Fun() function and printed the appropriate message.
