+/// In SHOUTY_SNAKE_CASE, word boundaries are indicated by underscores and all
+/// words are in uppercase.
+///
+/// ## Example:
+///
+/// ```rust
+/// use heck::ShoutySnakeCase;
+///     
+/// let sentence = "That world is growing in this minute.";
+/// assert_eq!(sentence.to_shouty_snake_case(), "THAT_WORLD_IS_GROWING_IN_THIS_MINUTE");
+/// ```

+
+/// Oh heck, ShoutySnekCase is an alias for ShoutySnakeCase. See ShoutySnakeCase
+/// for more documentation.
