+/// This trait defines a shouty kebab case conversion.
+///
+/// In SHOUTY-KEBAB-CASE, word boundaries are indicated by hyphens and all
+/// words are in uppercase.
+///
+/// ## Example:
+///
+/// ```rust
+/// use heck::ToShoutyKebabCase;
+///
+/// let sentence = "We are going to inherit the earth.";
+/// assert_eq!(sentence.to_shouty_kebab_case(), "WE-ARE-GOING-TO-INHERIT-THE-EARTH");
+/// ```

+    }
+}
+
+/// This wrapper performs a kebab case conversion in [`fmt::Display`].
+///
+/// ## Example:
+///
+/// ```
+/// use heck::AsShoutyKebabCase;
+///
+/// let sentence = "We are going to inherit the earth.";
+/// assert_eq!(format!("{}", AsShoutyKebabCase(sentence)), "WE-ARE-GOING-TO-INHERIT-THE-EARTH");
