Luna::move_assign_range

template <typename _Iter1, typename _Iter2>
auto move_assign_range(_Iter1 first, _Iter1 last, _Iter2 d_first) -> enable_if_t<!Impl::move_assign_range_is_value_type_trivial< _Iter1, _Iter2 >::value, _Iter2 >

Performs move assignment operation on every object in the destination range using the corresponding object in the source range.

Parameters

• in first

  An iterator to the first object to be moved from.

• in last

  An iterator to one-past-last object to be moved from.

• in d_first

  An iterator to the first object to be assigned.

Return value

Returns an iterator to the one-past-last object to be assigned.

Remark

The move operation is performed from first to last, the first element in destination range must not in the source range. memmove is used to move the data directly if:1. Both _Iter1 and _Iter2 are pointer types.

1. value_type of _Iter1 and _Iter2 is same.

2. value_type is trivially copy assignable and trivially move assignable. (If the type is trivially move assignable but not trivially copy assignable, the move assignment operator behaves the same as the copy assignment operator.) Otherwise, the move assignment operator is called for every object to move assign objects in destination range.
