Turn pinyin written with tone numbers and turn it into pinyin with node marks. prettify_pinyin accepts input in the CC-CEDICT pinyin format (space separated syllables with tone numbers at the end of each syllable), for example: "ni3 hao3" will get turned into "nǐ hǎo".
This project is a Rust translation of John Heroy's prettify-pinyin JavaScript project.
```rust extern crate prettify_pinyin;
use prettify_pinyin::prettify;
let test = String::from("ma1 ma2 ma3 ma4 ma"); let formatted: String = prettify(test);
println!("{}", formatted); // --> mā má mǎ mà ma ```
