std::swap(std::array) (3) Linux Manual Page

std::swap(std::array) – std::swap(std::array)

Synopsis

template <class T, std::size_t N>
(since C++ 11)

    void swap(array<T, N> &lhs, (until C++ 17)

                                    array<T, N> &rhs);

template <class T, std::size_t N>
(since C++ 17)

    void swap(array<T, N> &lhs, (until C++ 20)

                                    array<T, N> &rhs) noexcept(/* see below */);

template <class T, std::size_t N>

constexpr void swap(array<T, N> &lhs, (since C++ 20)

                                          array<T, N> &rhs) noexcept(/* see below */);

Specializes the std::swap algorithm for std::array. Swaps the contents of lhs and rhs. Calls lhs.swap(rhs).
This overload only participates in overload resolution if N == 0 or std::is_swappable<T>::value is true. (since C++17)

Parameters

lhs, rhs – containers whose contents to swap

Return value

(none)

Complexity

Linear in size of the container.

Exceptions

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