Overview

This class is instantiated by the Launcher and used to boot and serve a Ruby application when no puma “workers” are needed i.e. only using “threaded” mode. For example $ puma -t 1:5

At the core of this class is running an instance of Server which gets created via the start_server method from the Runner class that this inherits from.
