destiny

一个简单的用于解析和评估桌面游戏中的骰子字符串的库。

示例

使用 destiny::parse_dice_string 投掷一些骰子

use destiny::parse_dice_string;

println!("{}", parse_dice_string("1d4"));
println!("{}", parse_dice_string("1d6"));
println!("{}", parse_dice_string("2d6"));
println!("{}", parse_dice_string("1d8 + 3"));
println!("{}", parse_dice_string("1d6 + 2d8"));

使用 destiny::DiceDistribution 计算分布

use destiny::DiceDistribution;

let dd = DiceDistribution::new("2d6");
dd.ptable();

/* this will output:
