std::swap(std::basic_string)

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)))
