How can I check that a Chinese sentence written in Chinese characters (汉字) matches with the sentence in pinyin (拼音)? Well, first I have to parse the pinyin (which is not so easy), then I have to iterate over the Chinese characters... wait, 儿 might or might not stick to the previous syllable...
This crate resolves all that mess. With this crate, all you need is:
use match_pinyin_with_hanzi::match_pinyin_with_hanzi;
match_pinyin_with_hanzi(
"māmā qí mǎ, mǎ màn, māma mà mǎ.",
"妈妈骑马，马慢，妈妈骂马。"
).unwrap();Note that both māmā and māma are allowed to match with 妈妈. This crate assumes that any syllable can lose its tone, so it is perfectly okay to match a toneless pinyin to the Chinese character.
