The library does define a basic (or default) vector type:

There are independent reasons why people may want to define their own
vector types or may already have several different vector types on their
hands. QVM can be used to make such types compatible with each other. In
addition, QVM itself emits many different vector types, e.g. see
http://www.revergestudios.com/boost-qvm/view_proxy.html.
