NewComponentManagerBuilder returns a new ComponentManagerBuilder.

RunComponent repeatedly starts components returned from the given ComponentFactory, shutting them down when they encounter irrecoverable errors and passing those errors to the given error handler.

ErrComponentShutdown is returned by a component which has already been shut down.

ComponentManager is used to manage the worker routines of a Component, and implements all of the methods required by the Component interface, abstracting them away from individual implementations.

Component represents a component which can be started and stopped, and exposes channels that close when startup and shutdown have completed.

ComponentManagerBuilder provides a mechanism for building a ComponentManager.

ComponentWorker represents a worker routine of a component.

OnError reacts to an irrecoverable error It is meant to inspect the error, determining its type and seeing if e.g.

ReadyFunc is called within a ComponentWorker function to indicate that the worker is ready ComponentManager's Ready channel is closed when all workers are ready.
