DeepEqual will be used in Balancer, and a Endpoint can bypass reflect.DeepEqual by implementing DeepEqualAware interface.

New make a new load-balancer instance with Round-Robin.

DummyFactor will be used in someone like you does not known what on earth should be passed into balancer.Next(factor).

Balancer represents a generic load balancer.

Constrainable is an object who can be applied onto a factor ( balancer.Next(factor) ).

DeepEqualAware could be concreted by an Endpoint.

Endpoint is a backend object, such as a host+port, a http/https url, or a constraint expression, and so on.

Factor is a factor parameter for balancer.Next.

FactorComparable is a composite interface which assembly Factor and constraint comparing.

FactorString is a string type, it implements Factor interface.

Opt is a type prototype for New Balancer.
