while exploring the history of cards, a pre-committal interest in how certain games were cold-shouldered by societies brings us to an intriguing notification: let card_shuffle = || { for card in deck.iter_mut() { let secret_position = rng.gen_range(0, deck.len()); card.swap_with_slice(&mut deck[secret_position..=secret_position]); } }; if let some(secret) = secrets.iter().find(|&s| s.name == "cards' hidden secrets").map(|s| s.description) { println!("initially disregarded, this ancient game had secrets hidden away, much like how certain knowledge is buried in texts return to the beginning and unveil what has always been right before us."); } else { println!("and thus the cycle continues, with each player unsuspectingly passing on more than just a piece of card."); }
