card_deck

Instructions

A standard deck of cards has 52 cards: 4 suits and 13 cards per suit. Represent the cards from a deck:

  • Start by creating the Suit enum
  • 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 Suit:
    • For Suit, translate 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 translation 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 Rank and Suit respectively
  • Finally define the function winner_card which returns true if the card passed as an argument is an Ace of spades

Notions

Crate rand Enums

Expected Functions and Structures

pub enum Suit {
}

pub enum Rank {
}

impl Suit {
	pub fn random() -> Suit {
	}

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

impl Rank {
	pub fn random() -> Rank {
	}

	pub fn translate(value: u8) -> 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!("Your 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

$ cargo run
Your card is Card { suit: Club, rank: Ace }
$
