You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: dummy_code.rs
    path of file: ./repos/fastn/fastn-core/tests/16-include-processor/input/code
    
    the code of the file until where you have to start completion: // ANCHOR: all
// ANCHOR: io
use std::io;
// ANCHOR_END: io

// ANCHOR: main
fn main() {
    
    
fn main() {
    // ANCHOR_END: main
    // ANCHOR: print
    println!("Guess the number!");

    println!("Please input your guess.");
    // ANCHOR_END: print

    // ANCHOR: string
    let mut guess = String::new();
    // ANCHOR_END: string

    // ANCHOR: read
    io::stdin()
        .read_line(&mut guess)
        // ANCHOR_END: read
        // ANCHOR: expect
        .expect("Failed to read line");
    // ANCHOR_END: expect

    // ANCHOR: print_guess
    println!("You guessed: {}", guess);
    // ANCHOR_END: print_guess
}
