We could alternatively use the wildcard syntax to include everything from `greetings` into the current scope: `pub use self::greetings::*`. +What about the `self`? Well, by default, `use` declarations are absolute paths, +starting from your crate root. `self` makes that path relative to your current +place in the hierarchy instead. There's one more special form of `use`: you can +`use super::` to reach one level up the tree from your current location. Some +people like to think of `self` as `.` and `super` as `..`, from many shells' +display for the current directory and the parent directory. + Also, note that we `pub use`d before we declared our `mod`s. Rust requires that `use` declarations go first. |
