I've written a lot of code using std::vector<T> and std::vector<T>::iterator. Now I've decided to replace the vector container with a circular buffer from boost, namely boost::circular_buffer<T>.

Of course now the compiler will complain for every function that uses std::... where I'm passing the boost::... counterpart. Do I have to rewrite all functions now? I'm asking since the container from boost works exactly the same. Also the Boost documentation states the following:

The circular_buffer is a STL compliant container. It is a kind of sequence similar to std::list or std::deque.

What does the "STL compliant" part mean? Is it referring to what I would like to do (interchangability) or is it simply a mental note for programmers, that the containers work the same way in boost as in STL?
