//! **Deprecated: The [pinyin](https://crates.io/crates/pinyin) crate [has been rewritten](https://github.com/mozillazg/rust-pinyin/pull/36), use it instead.**
//!
//! ------------------
//!
//! Example:
//!
//! ```
//! extern crate pinyin_order;
//!
//! use pinyin_order::as_pinyin;
//!
//! fn main() {
//!     let mut l = vec!["中文", "中国", "abc", "重工", "abc中文"];
//!     l.sort_by_key(|s| as_pinyin(s));
//!     assert_eq!(l, vec!["abc", "abc中文", "中国", "中文", "重工"]);
//! }
//! ```
