std::permutable

Defined in header <iterator>
template< class I >
concept permutable =
    std::forward_iterator<I> &&
    std::indirectly_movable_storable<I, I> &&
    std::indirectly_swappable<I, I>;
(since C++20)

The concept permutable refines std::forward_iterator by adding requirements for reordering through moves and swaps.

Semantic requirements

I models permutable only if all concepts it subsumes are modeled.
