Deduction guides(C++17)

template< class CharT, class Traits > void swap( basic_regex<CharT,Traits> &lhs, basic_regex<CharT,Traits> &rhs ) noexcept;		(since C++11)

Overloads the std::swap algorithm for std::basic_regex. Exchanges the state of lhs with that of rhs. Effectively calls lhs.swap(rhs).

Parameters
