Rust刷題黑科技開源了
去年解決了Rust刷題的關鍵問題 Rust將取代C/C++成為刷題的首選 。後來一直懶的做題，於是代碼一直爛在那裡，直到有人提了個問題 有哪些支持rust的刷題在線網站，如hackerrank 想想還是開源吧。
結果更新rust版本後，發現了個問題，Cargo.toml 里 rpath = true 不知道為啥不起作用了。假如 linkbc 用不了 (linkbc主要用於強行lto)，請自行 patchelf --set-rpath /path/to/nightly-xxx/lib linkbc 。
Rust部分在 bhuztez/porus
用於自動提交代碼的python庫 bhuztez/ix (內含自動壓縮全是彙編代碼C語言代碼的黑科技，以免代碼長度超過某些OJ的上限，在porus目錄下，看 python3 -mix generate solutions/HR/solve-me-first.rs 運行結果就知道了)
有任何問題或者建議直接開Issue好了

舉個簡單的例子，上面提到的運行結果長這樣
