Description of the problem:
Listing 5-6 code reads:

fn main() {
    // --snip--

    let user2 = User {
        active: user1.active,
        username: user1.username,
        email: String::from("another@example.com"),
        sign_in_count: user1.sign_in_count,
    };
}

Listing 5-6: Creating a new User instance using one of the values from user1

It seems to me that we we are copying all the fields from user1 into user2 and only changing one of them - email.

Suggested fix:

Maybe the description under the code should say:

Listing 5-6: Creating a new User instance using all but one of the values from user1
