| //! The Rust Prelude. |
| //! |
| //! Rust comes with a variety of things in its standard library. However, if |
| //! you had to manually import every single thing that you used, it would be |

| //! The *prelude* is the list of things that Rust automatically imports into |
| //! every Rust program. It's kept as small as possible, and is focused on |
| //! things, particularly traits, which are used in almost every single Rust |
| //! program. |
