std::array<T,N>::swap: std::array<T,N>::swap


std::array<T,N>::swap - std::array<T,N>::swap


void swap( array& other ) noexcept(/* see below */); (since C++11)
                                                                (until C++20)
constexpr void swap( array& other ) noexcept(/* see below */); (since C++20)

Exchanges the contents of the container with those of other. Does not cause iterators and references to associate with the other container.


other - container to exchange the contents with

Return value



noexcept specification:
noexcept(noexcept(swap(std::declval<T&>(), std::declval<T&>()))) (until C++17)
In the expression above, the identifier swap is looked up in the same manner as the one used by the C++17 std::is_nothrow_swappable trait.
noexcept specification: (since C++17)

For zero-sized arrays,
noexcept specification:


Linear in size of the container.
