clippit 使 cargo clippy 的声音听起来像 Office 2003 的 Clippit 助手（即 "Clippy"）。

|   |         ^^ If this is intentional, prefix it with an underscore: `_pi`                                    |

|   Hint: consider using the constant directly.                                                                 |

| Hmmm... `problematic-code` (bin "problematic-code") generated 2 warnings.                                     |
| Let's fix `problematic-code` (bin "problematic-code")!                                                        |
