How to use stdin().lines() inside a for loop in Rust

Answer 1

use std::io::stdin;
use std::io::BufRead;
use std::io::BufReader;
 
fn main() {
    println!("Enter numbers, 42 to exit:");
    
    for line in BufReader::new(stdin()).lines() {
        match line {
            Ok(ref s) if s == "42" => break,
            Ok(ref s) => println!("{}", s),
            _ => continue
        }
    }
}



/*
run:

Enter numbers, 42 to exit:
5
