use std::fs::File;
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)}}}
}
