// 1. Wow. Just...wow. Let's start cleaning this up by running `cargo fmt`.
|
|
|
|
// 2. `cargo fmt` is great, but it doesn't add blank lines where there are none. Go ahead and add
|
|
// some blank lines in places you think it would make sense.
|
|
|
|
// 3. Time to clean up! Run `cargo clippy`. Fix up all the warnings so `cargo clippy` is silent.
|
|
|
|
// Challenge: Clippy doesn't find *everything*. What else would you change to make this code better?
