use chinesedetection::ChineseDetection; use chinesedetection::ClassificationResult;
let language_detection = ChineseDetection::new();
println!("{}", languagedetection.classify("test")); // --> ClassificationResult::EN println!("{}", languagedetection.classify("shiyan")); // --> ClassificationResult::PY println!("{}", language_detection.classify("实验")); // --> ClassificationResult::ZH ```
