I'm looking for a good data structure that can maintain its elements sorted. Currently I'm trying Boost.Heap.

I frequently need to orderly traverse the data structure, find a element based on some property and update its priority when it matches. Boost.Heap priority queues provide ordered and non-ordered iterators. Element updates occurs through a element handle, a handle can be obtained from a ordinary non-ordered iterator, but not directly from a ordered one as in the following example:

#include <iostream>
#include <algorithm>
#include <boost/heap/fibonacci_heap.hpp>

using namespace boost::heap;

int main()
{
    fibonacci_heap<int> fib_heap;

    fib_heap.push(1);
    fib_heap.push(2);
    fib_heap.push(3);

    for(auto i = fib_heap.ordered_begin(); i != fib_heap.ordered_end(); ++i)
    {
        auto h = fibonacci_heap<int>::s_handle_from_iterator(i);
        if(*h == 3)
        {
            fib_heap.increase(h, *h + 2);
            break;
        }
    }

    std::for_each(fib_heap.ordered_begin(), fib_heap.ordered_end(),
    [](const int &e)
    {
        std::cout << e << std::endl;
    });
}
How can I orderly traverse the queue and update an element in the traversal?

Note that I leave traversal after the update.

(Suggestions of alternative libraries for such purpose are welcome)
