+///
+/// In UpperCamelCase, word boundaries are indicated by capital letters,
+/// including the first word.
+///
+/// ## Example:
+///
+/// ```rust
+/// use heck::ToUpperCamelCase;
+///
+/// let sentence = "We are not in the least afraid of ruins.";
+/// assert_eq!(sentence.to_upper_camel_case(), "WeAreNotInTheLeastAfraidOfRuins");
+/// ```

+impl ToUpperCamelCase for str {
+    fn to_upper_camel_case(&self) -> String {
+        AsUpperCamelCase(self).to_string()
+    }
+}
+
+/// ToPascalCase is an alias for ToUpperCamelCase. See ToUpperCamelCase for more
+/// documentation.

+/// assert_eq!(format!("{}", AsUpperCamelCase(sentence)), "WeAreNotInTheLeastAfraidOfRuins");
