Defined in header `<iterator>`
template < class In, class Out > concept indirectly_movable_storable = std::indirectly_movable <In, Out> && std::indirectly_writable <Out, std::iter_value_t <In>> && std::movable < std::iter_value_t <In>> && std::constructible_from < std::iter_value_t <In>, std::iter_rvalue_reference_t <In>> && std::assignable_from < std::iter_value_t <In> &, std::iter_rvalue_reference_t <In>> ;		(since C++20)

The indirectly_movable_storable concept specifies the relationship between an indirectly_readable type and an indirectly_writable type. In addition to indirectly_movable, this concept specifies that the move from the indirectly_readable

Semantic requirements

In and Out model std::indirectly_movable_storable<In, Out> only if given a dereferenceable value i of type In

After the definition std::iter_value_t <In> obj( ranges::iter_move (i) ) ; , obj is equal to the value previously denoted by *i
if std::iter_rvalue_reference_t<In> is an rvalue reference type, *i is placed in a valid but unspecified state after the initialization of obj

Equality preservation

Expressions declared in requires expressions of the standard library concepts are required to be equality-preserving

indirectly_movable (C++20)	specifies that values may be moved from an `indirectly_readable` type to an `indirectly_writable` type (concept)
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)
