Instructions

Represent cards from a desk

• A standard deck of cards has 52 cards: 4 suits and 13 cards per suit

• Start by creating the Suit enum and implement the associated function random which returns a random Suit (Heart, Diamond, Spade or Club)

• Then create the Rank enum that can have the value Ace, King, Queen, Jack, and Number associated to an u8 value to represent the ranks 2 through 10 After create an associated function to Rank called Random that returns a random Rank

• Finally create a structure name Card which has the fields suit and rank

Define:

The associated function translate for Rank and Suite

• for Suit, tranlate makes the translation between an integer value (u8) and the suit of a card (1 -> Heart, 2 -> Diamonds, 3 -> Spade, 4 -> Club)
• for Rank, translate makes the tranlation between an integer value (u8) and the rank ( 1 -> Ace, 2 -> 2, .., 10 -> 10, 11 -> Jack, 12 -> Queen, 13 -> King)

The associated function random for Rank and Suit which returns a random rand and suit respectively

Finally define the function winner_card that returns true if the card passed as an argument is an Ace of spades

Expected Functions and Structures

pub fn random() -> Suit {
}

pub fn translate(value: u8) -> Suit {
}

pub fn random() -> Rank {
}

pub fn traslate(value: u8) -> Rank {
}

pub enum Suit {
}

pub enum Rank {
}

pub struct Card {
	pub suit: Suit,
	pub rank: Rank,
}

Usage

Here is a program to test your function

fn main() {
	let your_card = Card {
		rank: Rank::random(),
		suit: Suit::random(),
	};

	println!("You're card is {:?}", your_card);

	// Now if the card is an Ace of Spades print "You are the winner"
	if card_deck::winner_card(your_card) {
		println!("You are the winner!");
	}
}

And its output

You're card is Card { suit: Club, rank: Ace }
