Description of the problem:
Listing 7-18 contains:
use std::{cmp::Ordering, io};

Suggested fix:
From my understanding it should be use std::cmp::{Ordering, io};

Sorry, I'm not sure why you got that impression because what you've suggested doesn't compile: https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=47ce49e6efffbdf53eb1ba6720fdce0e

The io module is under std, not std::cmp.
