//! Hemoglobin is a library containing data structures and functions useful for the card game Bloodless. It is used by [Hemolymph](http://hemolymph.net), the official card search engine.
//!
//! The two datastructures are `Card`, which represents a card and `CardId`, which represents a card pattern. Card pattern in this library do not represent card patterns as defined by the game's rules, but rather as a more general structure for matching against cards.
//!
//! This library contains the search functions used by Hemolymph.
