type KeyValueServer

type KeyValueServer interface {

	// Start starts the server on a distinct port, instantiates the database
	// and begins listening for incoming client connections. Start returns an
	// error if there was a problem listening on the specified port.
	//
	// This method should NOT block. Instead, it should spawn one or more
	// goroutines (to handle things like accepting incoming client connections,
	// broadcasting messages to clients, synchronizing access to the server's
	// set of connected clients, etc.) and then return.
	//
	// This method should return an error if the server has already been closed.
	Start(port int) error

	// Count returns the number of clients currently connected to the server.
	// This method must not be called on an un-started or closed server.
	Count() int

	// Close shuts down the server. All client connections should be closed immediately
	// and any goroutines running in the background should be signaled to return.
	Close()
}
