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

From cppreference.com
< cpp‎ | container‎ | array
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.

Parameters

other - container to exchange the contents with

Return value

(none)

Exceptions

noexcept specification:  
noexcept(noexcept(swap(std::declval<T&>(), std::declval<T&>())))

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.

(until C++17)
noexcept specification:  
(since C++17)
For zero-sized arrays,
noexcept specification:  
noexcept
  

Complexity

Linear in size of the container.
