use std::io::{BufRead, BufReader};
use regex::{Regex};


fn main() {
    let f = File::open("F:\\0-X-RUST\\1-systematic\\ch2-fileRead\\data\\test.csv").unwrap();
    let mut reader = BufReader::new(f);

    let re = Regex::new("45asd").unwrap();


    for line in reader.lines(){
        let line = line.unwrap();
        println!("{}", line);
        let c_s = re.find(&*line);

        match c_s {
            None => {println!("未匹配到:45asd")}
            Some(_) => { print!("包含{:?}", c_s)}
        }
    }
}
