Rust中如何读取一个CSV文件？

use csv::Error;

fn main() -> Result<(), Error> {

let csv_data = "
101,Edith,Masao,Edith.Masao@mail.io,Colombia,doctor
102,Kellen,Yusuk,Kellen.Yusuk@mail.io,Nicaragua,police officer
";

let mut reader = csv::Reader::from_reader(csv_data.as_bytes());

for row in reader.records() {
  let row = row?;
  println!(
    "id {} | firstname: {} | lastname: {} | email: {} | country: {} | profession: {} |",

    &row[0],
    &row[1],
    &row[2],
    &row[3],
    &row[4],
    &row[5],
    );
 }
 Ok(())
}
