[edit]

Defined in header`<iterator>`
template<class In,class Out> concept indirectly_copyable= std::indirectly_readable<In>&& std::indirectly_writable<Out,std::iter_reference_t<In>>;		(since C++20)

Theindirectly_copyable concept specifies the relationship between anindirectly_readable type and a type that isindirectly_writable. Theindirectly_writable type must be able to directly copy the object that theindirectly_readable type references.

indirectly_movable (C++20)	specifies that values may be moved from an`indirectly_readable` type to an`indirectly_writable` type (concept)[edit]
indirectly_copyable_storable (C++20)	specifies that values may be copied from an`indirectly_readable` type to an`indirectly_writable` type and that the copy may be performed via an intermediate object (concept)[edit]
