Trait Implementations

impl CardCollection for Cascade

fn add_card(&self, card: Card) -> Result<Cascade, ()>

Creates a copy of the CardCollection, but with an additional card added. Fails if the card cannot be put into the collection.

fn pop_card(&self) -> Vec<(Cascade, Card)>

Creates all possible versions of the CardCollection where one card has been removed. Each returned CardCollection is paired with the removed card. If no card can be removed according to the rules, an empty Vec is returned.
