## card_deck
### Instructions
A standard deck of cards has 52 cards: 4 suits with 13 cards per suit.
Represent the cards from a deck:
- Create an `enum` to represent the `Suit`.
- Implement the associated **function** `random`, which returns a random `Suit` (`Heart`, `Diamond`, `Spade` or `Club`).
- Create a `Rank` enum. For ace and face cards, it can be one of `Ace`, `King`, `Queen` or `Jack`. For the values from 2 to 10, it can have a `Number` value associated to a `u8`.
- Create an associated **function** to `Rank` called `Random` that returns a random `Rank`.
- Create a structure name `Card` which has the fields `suit` and `rank`.
Define:
- The associated **function** `translate` for `Rank` and `Suit`:
- For `Suit`, `translate` converts an integer value (`u8`) to a suit (1 -> Heart, 2 -> Diamonds, 3 -> Spade, 4 -> Club).
- For `Rank`, `translate` converts an integer value (`u8`) to a rank ( 1 -> Ace, 2 -> 2, .., 10 -> 10, 11 -> Jack, 12 -> Queen, 13 -> King).
- The associated **function** `random` for `Rank` and `Suit` 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.
### Dependencies
rand = "0.8.5"
### Expected Functions and Structures
```rust
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,
}
pub fn winner_card(card: &Card) -> bool {
}
```
### Usage
Here is a program to test your function
```rust
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
```console
$ cargo run
Your card is Card { suit: Club, rank: Ace }
$
```
