Classes🔗

Name
class iox::popo::BasePort
this class is the base for all ports. it is constructed from a member pointer and is only movable. only movable rational: a port has only one member, a pointer to its data. if a port is copied then both ports would work on the same data even though these are two independent copies. this would case a weird shared state, race conditions and so on
