为什么没有boost :: container :: queue？

Question

I am starting to work with Boost, and I am looking through the several libraries it holds.

I have noted that boost::container defines almost all standard containers, but not the queue .

I don't have found any reference to it; so I am wondering why there is only deque . I want to test the replacement of STL containers with boost ones, and I was told it would be possible...

Thanks in advance for any explanation on this subject.

std::queue isn't a container, it's a wrapper. It consumes a container and provides a non-container (simplified) interface.

The Boost version of std::queue<T> (which actually means std::queue<T, std::deque<T> > , via a default template argument) is std::queue<T, boost::container::deque<T> > .
