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.

[edit] Semantic requirements

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