template< class CharT, class Traits, class Alloc > void swap( std::basic_string<CharT, Traits, Alloc> &lhs,            std::basic_string<CharT, Traits, Alloc> &rhs );		(C++17 前)
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 */);		(C++17 起)

为 std::basic_string 特化 std::swap 算法。交换 lhs 与 rhs 的内容。等价于 lhs.swap(rhs) 。

参数

lhs, rhs

-

要交换内容的 string

返回值

（无）

复杂度

常数。

异常 noexcept 规定：   noexcept(noexcept(lhs.swap(rhs)))

(C++17 起)
