+elements to be yielded which borrow from the iterator itself.  That means, for
+example, that the @code{std::io::Lines} iterator must allocate a new
+@code{String} for each line rather than reusing an internal buffer.  The
+@code{StreamingIterator} trait instead provides access to elements being
+iterated over only by reference rather than by value.")
