constexpr default_searcher(ForwardIterator1 pat_first, ForwardIterator1 pat_last,
                           BinaryPredicate pred = BinaryPredicate();

Effects: Constructs a default_searcher object, initializing pat_first_ with pat_first, pat_last_ with pat_last, and pred_ with pred.

Throws: Any exception thrown by the copy constructor of BinaryPredicate or ForwardIterator1.

🔗

template<class ForwardIterator2>
  constexpr pair<ForwardIterator2, ForwardIterator2>
    operator()(ForwardIterator2 first, ForwardIterator2 last) const;

Effects: Returns a pair of iterators i and j such that

(3.1)
i == search(first, last, pat_first_, pat_last_, pred_), and
(3.2)
if i == last, then j == last, otherwise j == next(i, distance(pat_first_, pat_last_).
