+}Replacer describes types that can be used to replace matches in a string.
+Required Methods
+
+
+ fn reg_replace<'a>(&'a mut self, caps: &Captures) -> Cow<'a, str>
Returns a possibly owned string that is used to replace the match
+corresponding to the caps capture group.
The 'a lifetime refers to the lifetime of a borrowed string when
+a new owned string isn't needed (e.g., for NoExpand).
Provided Methods
+
+
+ fn no_expand<'a>(&'a mut self) -> Option<Cow<'a, str>>
Returns a possibly owned string that never needs expansion.
