Rust Program: Enum Colors

Rust Structs and Enums: Exercise-8 with Solution

Write a Rust program that implements an enum Color with variants representing different colors (e.g., Red, Green, Blue).

Sample Solution:

Rust Code:

// Define an enum named 'Color' with variants representing different colors
#[derive(Debug)]
enum Color {
    Red,
    Green,
    Blue,
}

fn main() {
    // Create variables representing different colors
    let red = Color::Red;
    let green = Color::Green;
    let blue = Color::Blue;

    // Print the values of the variables representing colors
    println!("Red: {:?}", red);
    println!("Green: {:?}", green);
    println!("Blue: {:?}", blue);
}

Output:

Red: Red
Green: Green
Blue: Blue

Explanation:

The above Rust code defines an enum called 'Color', which represents different colors ('Red', 'Green', and 'Blue'). Inside the 'main' function, it creates variables for each color variant and prints out their values using the 'println!' macro with the '{:?}' format specifier, which is enabled by deriving the 'Debug' trait for the 'Color' enum. This allows the program to print the enum variants along with their associated data for debugging purposes.
