Card

The Card is a simple class in both languages (an enum in Dart and a single-member anonymous tuple in Rust), represented by a single small integer I call an Ordinal, in the range 1..63.

I do not represent cards with separate data items for Rank and Suit: the ordinals are arranged so that they can be computed quickly when needed, but are rarely needed as most comparisons can be done with whole ordinals alone. The card class has methods rank and suit to retrieve these if needed.

Methods of the card class include classifiers: things like isAce(), isJoker(), isRed(), and the same kinds of conversions to/from text that are available in the suit and rank classes.
