Day 15: Crafting Cars in Rust – A Symphony of Geeky Dialogues and Struct Choreography 🚗🛠️

Ahoy, fellow code weavers! Today, on Day 15 of my #100DaysOfCode Rust escapade, I decided to embark on a code crafting journey, attempting to build a car using user input, a sprinkle of capitalization sorcery, and the dance of structs and enums. Let's dive into the geeky dialogue and struct choreography! 🌐💬

The Struct Ballad – Where Fields Dance in Harmony 🏰💃

In the grand realm of Rust, the Car struct emerges as the master choreographer. Its fields – color, transmission, brand – waltz together, crafting the very essence of our digital vehicle.

struct Car {
    color: String,
    car_type: String,
    transmission: Transmission,
    convertible: bool,
    brand: String,
}

// Enum for Car transmission type
#[derive(PartialEq, Debug)]
enum Transmission {
    Manual,
    SemiAuto,
    Automatic,
}

This elegantly crafted struct defines the essence of a car, blending seamlessly with the symphony of Rustic code.

The Geeky Dialogue – A Conversation with Code Monologues 🎭💻

No Rustic car would be complete without a user dialogue. The take_user_input function takes on the role of a coding conversationalist, engaging in a tête-à-tête with users, capturing their dreams and desires for the perfect digital ride.

fn take_user_input(user_input: &mut String) -> String {
    io::stdin()
        .read_line(user_input)
        .expect("Failed to read the input");

    user_input.trim().to_string()
}

This function echoes the whispers of the user, ready to mold their digital dreams into code reality.

The Capitalization Chronicles – String Prestidigitation Unveiled 🌟🎩

In the mystical realm of Rust, the capitalize library takes center stage. Strings transform into eloquent titles, as the colors, brands, and types undergo a spell of capitalization brilliance.

let car_color = car_color.trim().to_string().capitalize();
let car_type = car_type.trim().to_string().capitalize();

The Car Factory Ballet – Struct Choreography in Action 🎶🚗

The car_factory function steps onto the stage, the maestro of our digital ballet. It conducts the symphony of user aspirations, weaving them into a tangible creation – the Car struct.

fn car_factory(
    color: String,
    transmission: Transmission,
    convertible: bool,
    brand: String,
    car_type: String,
) -> Car {
    Car {
        color,
        transmission,
        convertible,
        brand,
        car_type,
    }
}

This function symbolizes the dance of the digital artisans, molding user aspirations into a structured masterpiece.

The Grand Finale – A Digital Car Unveiling with Pizzazz 🚀🎉

As the final curtain rises, the crafted car takes center stage. Its unique attributes – brand, type, color, transmission, and convertible allure – are revealed in a dazzling spectacle.

println!(
    "Your car has been built with the following specifications:\nCar brand: {}, Type: {}, Color: {}, Transmission: {:?}, Convertible: {}",
    car.brand, car.car_type, car.color, car.transmission, car.convertible
);

        car.brand, car.car_type, car.color, car.transmission, car.convertible
    );
}

fn car_factory(
    color: String,
    transmission: Transmission,
    convertible: bool,
    brand: String,
    car_type: String,

    // All new cars always have zero mileage
    Car {
        color,
        transmission,
        convertible,
        brand,
        car_type,
