    constexpr void swap( indirect& other ) noexcept(/* see below */);
    		(since C++26)

    Swaps the contents with those of other.

    In the description below, swap_allocators refers to std::allocator_traits<Allocator>::propagate_on_container_swap::value.

    Swaps the states of *this and other, exchanging owned objects or valueless states.

    • If swap_allocators is true, then executes using std::swap;
      swap(alloc , other.alloc );      .
    • Otherwise, the allocators are not swapped.

    If one of the following conditions is satisfied, the behavior is undefined:

    • swap_allocators is true, and Allocator does not satisfy the requirements of Swappable.
    • swap_allocators is false, and get_allocator() == other.get_allocator() is false.

    Parameters

    other - the indirect object to exchange the contents with

    Exceptions

    noexcept specification:  
    noexcept(std::allocator_traits<Allocator>::propagate_on_container_swap::value || std::allocator_traits<Allocator>::is_always_equal::value)
