文字编码检测库，累计下载量超过10W。配合encoding库，可以正确读取各种编码的文本文件。使用示例：use chardet;use std::fs::OpenOptions;use std::io::prelude::*;use encoding::DecoderTrap;use encoding::label::encoding_from_whatwg_label;// open text filelet mut fh = OpenOptions::new().read(true).open(filepath).expect( "Could not open file",);let mut reader: Vec = Vec::new();// read filefh.read_to_end(&mut reader).expect("Could not read file");// detect charset of the filelet result = detect(&reader);// result.0 Encode// result.1 Confidence// result.2 Language// decode file into utf-8let coder = encoding_from_whatwg_label(charset2encoding(&result.0));if coder.is_some() { let utf8reader = coder.unwrap().decode(&reader, DecoderTrap::Ignore).expect("Error");}
