trait NodeT[Req, Rep] extends ServiceFactory[Req, Rep]

The base type of nodes over which load is balanced. Nodes define the load metric that is used; distributors like P2C will use these to decide where to balance the next request.

    Permalink

    Reserve the use of a given service instance.

    Reserve the use of a given service instance. This pins the underlying channel and the returned service has exclusive use of its underlying connection. To relinquish the use of the reserved Service, the user must call Service.close().

    Apply f on created services, returning the resulting Future in their stead.

    Apply f on created services, returning the resulting Future in their stead. This is useful for implementing common factory wrappers that only need to modify or operate on the underlying service.
