SingletonPool

Related Doc: package pool

class SingletonPool[Req, Rep] extends ServiceFactory[Req, Rep]

A pool that maintains at most one service from the underlying ServiceFactory -- concurrent leases share the same, cached service. A new Service is established whenever the service factory fails or the current service has become unavailable.

    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.
