+/// In Title Case, word boundaries are indicated by spaces, and every word is
+/// capitalized.
+///
+/// ## Example:
+///
+/// ```rust
+/// use heck::ToTitleCase;
+///
+/// let sentence = "We have always lived in slums and holes in the wall.";
+/// assert_eq!(sentence.to_title_case(), "We Have Always Lived In Slums And Holes In The Wall");
+/// ```

+
+/// This wrapper performs a title case conversion in [`fmt::Display`].
+///
+/// ## Example:
+///
+/// ```
+/// use heck::AsTitleCase;
+///
+/// let sentence = "We have always lived in slums and holes in the wall.";
+/// assert_eq!(format!("{}", AsTitleCase(sentence)), "We Have Always Lived In Slums And Holes In The Wall");
