NAME

std::permutable - std::permutable

Synopsis

Defined in header <iterator>
template< class I >

concept permutable =
std::forward_iterator<I> && (since C++20)
std::indirectly_movable_storable<I, I> &&

std::indirectly_swappable<I, I>;

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.
