Rust: I/O

Input/output in Rust is one of the things that confuses me, so I wanted to drop a quick tutorial on how to io in Rust.

use std::io::{self, Write};

fn main() {
    // To begin with, let us take an input value.
    print!("Type something... ");
    io::stdout().flush().unwrap();

    let mut input_1 = String::new(); // This will prompt a user to input something.
    io::stdin().read_line(&mut input_1).ok().expect("Failed to read line.");

    println!("You typed {}.", input_1);
}
