Deduction guides(C++17)

template< class T, std::size_t N > void swap( array<T,N>& lhs, array<T,N>& rhs );		(since C++11) (until C++17)
template< class T, std::size_t N > void swap( array<T,N>& lhs, array<T,N>& rhs ) noexcept(/* see below */);		(since C++17)

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

(since C++17)
