中文数字

将原始数字转换为中文数字，或将中文数字解析为原始数字。

该crate可以将Rust的原始数字数据类型转换为中文数字字符串。例如，123可以转换为一二三，一百二十三或壹佰貳拾叁。它支持繁体中文和简体中文，并支持不同的计数方法。此外，字符串中的中文数字可以解析为原始数字数据类型。

示例

use chinese_number::{ChineseCase, ChineseCountMethod, ChineseVariant, NumberToChinese, ChineseToNumber};

assert_eq!("一二三", 123i8.to_chinese_naive(ChineseVariant::Traditional, ChineseCase::Lower));

assert_eq!("壹佰貳拾參", 123i8.to_chinese(ChineseVariant::Traditional, ChineseCase::Upper, ChineseCountMethod::TenThousand).unwrap());
assert_eq!("壹佰贰拾叁", 123i8.to_chinese(ChineseVariant::Simple, ChineseCase::Upper, ChineseCountMethod::TenThousand).unwrap());

assert_eq!("一百二十三", 123i8.to_chinese(ChineseVariant::Traditional, ChineseCase::Lower, ChineseCountMethod::TenThousand).unwrap());
