fn alphanumeric_chars(&self) -> impl DoubleEndedIterator

Lazily iterates the alphanumeric characters only, without allocating a String. strip_non_alphanum is built on this; prefer this directly if you only need to scan or compare the filtered characters rather than build an owned copy. Double-ended, so callers needing to scan from the end can call .rev() on it.
