• Evaluates hands with any number of cards from 0 to 7
• Higher score is better

// cards are indexed 0->51 where index is 4 * rank + suit
let hand = Hand::empty() + CARDS[0] + CARDS[1];
let score = evaluate(&hand);

Equity Calculator

• Runs a multithreaded monte-carlo simulation to calculate range vs range equities
• Supports up to 6 players

Usage

use rust_poker::hand_range::{HandRange, get_card_mask};
use rust_poker::equity_calculator::EquityCalc;
let ranges = HandRange::from_str_arr(["AK,22+", "random"].to_vec());
let public_cards = get_card_mask("2h3d4c");
let n_games = 10000;
let n_threads = 4;
let equities = EquityCalc::start(&ranges, public_cards, n_threads, n_games);
