我正在尝试获取系统输入并检查用户是否输入了是或否.我的字符串转换是错误还是什么？if块不执行.

use std::io;

fn main() {
    let mut correct_name = String::new();
    io::stdin().read_line(&mut correct_name).expect("Failed to read line");
    if correct_name == "y" {
        println!("matched y!");
    } else if correct_name == "n" {
        println!("matched n!");
    }
}
