template< class CharT, class Traits, class Alloc >
void swap( basic_string<CharT, Traits, Alloc> &lhs, basic_string<CharT, Traits, Alloc> &rhs );

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

Contents

Parameters

lhs, rhs - strings whose contents to swap

Return value

(none)

Complexity

Constant.

Exceptions

noexcept specification:  
noexcept(noexcept(lhs.swap(rhs)))
 (since C++17)
