Typos in "The Guessing Game"

[theroseknight]

Brand new to Rust so I apologize if this is not the right place for something like this. I just finished "The Guessing Game" and noticed a small typo:

We can do that with three more lines. Here’s our new program:

The new three lines:

    let guess: u32 = guess.trim().parse()
        .expect("Please type a number!");

It appears the book was updated at some point to only contain two lines.

Similarly. in the following section. this could be a typo or possibly just confusing:

io::stdin().read_line(&mut guess).expect("failed to read line"); 

If we leave off calling these two methods, our program will compile, but we’ll get a warning:

The two methods could refer to .expect and panic!.

Nope, this is a typo. There used to be calls to ok() in there, and they were removed, but the English wasn't.
