struct boost::fusion::vector< T >

Adapter for Boost.Fusion vectors.

Modeled concepts

A Fusion vector is a model of the Sequence concept, and all the concepts it refines. That makes it essentially the same as a Hana tuple, although the complexity of some operations might differ from that of a tuple.
