template< class CharT, class Traits, class Alloc > void swap( std::basic_string<CharT, Traits, Alloc> &lhs,            std::basic_string<CharT, Traits, Alloc> &rhs );		(until C++17)
template< class CharT, class Traits, class Alloc > void swap( std::basic_string<CharT, Traits, Alloc> &lhs,            std::basic_string<CharT, Traits, Alloc> &rhs ) noexcept(/* see below */);		(since C++17)

Specializes the std::swap algorithm for std::basic_string. Swaps the contents of lhs and rhs. Equivalent to lhs.swap(rhs).

Parameters

lhs, rhs

-

strings whose contents to swap

Return value

(none)

Complexity

Constant.

Exceptions noexcept specification:   noexcept(noexcept(lhs.swap(rhs)))

(since C++17)
