Bug #: 51960
Summary: Missing move-assignment operator in
raw_storage_iterator
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: libstdc++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: valy...@gmail.com
It's interesting why raw_storage_iterator (
http://gcc.gnu.org/viewcvs/trunk/libstdc%2B%2B-v3/include/bits/stl_raw_storage_iter.h?revision=169421&view=markup
) doesn't provide move-assignment operator? Such an operator would allow moving
items to a raw memory instead of copying them. In this case the
raw_storage_iterator could be properly used with std::move()-like algorithms:
template <typename InputIterator, typename T>
void move_to_raw_buffer(InputIterator first, InputIterator last, T *raw_buffer)
{
std::move(first, last, std::raw_storage_iterator<T *, T>(raw_buffer));
}
Currently this results in items' copying instead of expected items' movement
due to the lack of move-assignment operator in the raw_storage_iterator
implementation.
