dou_dizhu

This crate is a Rust toolkit for the Chinese card game Dou Dizhu. It provides hand representation, category recognition, ordering, and validation at both compile time and runtime.

Features

• Hand representation
• All standard Dou Dizhu combinations
• Hand comparison by game rules
• Compile-time and runtime validation

Usage

Add this to your Cargo.toml:

[dependencies]
dou_dizhu = "0.1"

Then:

use dou_dizhu::{hand, Hand};

fn main() {
    // Compile-time evaluated hand
    let four_with_dual_solo: Hand = hand!(const {
        King: 4,
        Four,
        Five,
    });

    // Runtime evaluated hand
    let bomb: Hand = hand!({
        Three: {
            println!("evaluating bomb");
            4
        },
    }).unwrap();

    // A bomb beats four with dual solo
    assert!(four_with_dual_solo < bomb);
}
