Deck of Cards

This is a simple library implemented in Rust that models a deck of cards. You can use it to create a deck, shuffle it, deal cards one or multiple cards at a time.

Cargo import

You can use the module in the standard way by adding this to your Cargo.toml. Unless you have a reason not to, you should use the latest released version.

[dependencies]
deckofcards = "0.4"

API documentation

Once you've added a dependency you can get class documentation like so:

cargo doc

Usage

The Deck class contains zero or more Cards which are held in dealt or undealt piles. You can shuffle() the deck. You can deal_one() card or deal_many() cards. You can reset() to return dealt cards to the undealt pile.

use deckofcards::*;

let mut deck = Deck::new();

By default if you don't shuffle, your deck will be sorted by suit then rank. You can shuffle the deck using a randomized Knuth shuffle:

deck.shuffle();

You can deal cards out to a Vec<Card>:

let cards = deck.deal(5);

Or into the Hand object which provides additional sorting and filtering.

let mut hand = Hand::new();
deck.deal(&mut hand, 3);

Each card has a Rank and a Suit, both of which are strong enum types.

Cards can be compared, sorted and have helpers to print a long and short description using English notation, e.g. "Ace of Spades" or "AS".

Macros

The crate provides convenience card! and hand! macros for declaring cards or hands as text:

#[macro_use]
extern crate deckofcards;

//... A Card that is the King of Clubs
let card = card!("KC");
//... A Hand that is Ace of Spades, 3 of Diamonds, Queen of Clubs
let hand = hand!("AS", "3D", "QC");

Example

There is an example for you see how it works in examples/main.rs.

cargo run --example main

Tests

There are some 30 or so unit tests.
