Struct MakeBalance
pub struct MakeBalance<S, Req> { /* private fields */ }Constructs load balancers over dynamic service sets produced by a wrapped "inner" service.
This is effectively an implementation of MakeService except that it forwards the service
descriptors (Target) to an inner service (S), and expects that service to produce a
service set in the form of a Discover. It then wraps the service set in a Balance
before returning it as the "made" service.
See the module-level documentation for details on load balancing.
