rs-poker
RS Poker is a rust library aimed at being a good starting place for lots of poker rust code. Correctness and performance are the two main goals.
Documentation is uploaded here The crates.io page is here
Core
The Core module contains code that is not specific to different types of poker games. It contains:
- Suit type
- Value type
- Card type
- Deck
- Hand iteration
- Poker hand rank type
- Poker hand evaluation for five card hands.
- Poker hand evaluation for seven card hands.
The poker hand (5 card) evaluation will rank a hand in ~20 nanoseconds per hand. That means that 50 Million hands per second can be ranked. The seven card hand evaluation will rank a hand in < 25 ns.
The hand evaluation is is fully accurate, it does not rely on just single kicker. This allows for breaking ties on hands that are closer.
Holdem
The holdem module contains code that is specific to holdem. It currently contains:
- Starting hand enumeration
- Hand range parsing
- Monte Carlo game simulation helpers.
Testing
The code is pretty well tested and benchmarked. If you find something that looks like a bug please submit a pr with test code.
5 Card + Hand iteration has been used in conjunction with fuzzing to validate the seven card hand evaluation.
