Crate chinese_num 

Convert a decimal number to its Chinese form.

Examples

let s = chinese_num::to_chinese_num("121").unwrap();
assert_eq!(s, "一百二十一");

let s = chinese_num::to_chinese_num("1004000007000500").unwrap();
assert_eq!(s, "一千零四万亿零七百万零五百");

let s = chinese_num::to_chinese_num("123000520").unwrap();
assert_eq!(s, "一亿二千三百万零五百二十");

let s = chinese_num::to_chinese_num("1234070000123780000087006786520988800000").unwrap();
assert_eq!(s, "一千二百三十四万零七百亿零一十二万三千七百八十亿零八千七百亿六千七百八十六万五千二百零九亿八千八百八十万");

If the given string is not a number, or begins with “0”, None is returned:

let s = chinese_num::to_chinese_num("不是数字");
assert!(s.is_none());

let s = chinese_num::to_chinese_num("020");
assert!(s.is_none());
