std::indirectly_movable_storable
<iterator>
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>> &&
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 type can be performed via an intermediate object.
[edit] 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));,
objis equal to the value previously denoted by *i, and - 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.
[edit] Equality preservation
Expressions declared in requires expressions of the standard library concepts are required to be equality-preserving (except where stated otherwise).
