	Name          string // Name of the event log or channel.
	RemoteAddress string // Remote computer to connect to. Optional.

	API string // Name of the API to use. Optional.
}

Config is the configuration data used to instantiate a new EventLog.

type EventLog

type EventLog interface {
	// Open the event log. recordNumber is the last successfully read event log
	// record number. Read will resume from recordNumber + 1. To start reading
	// from the first event specify a recordNumber of 0.
	Open(recordNumber uint64) error

	// Read records from the event log.
	Read() ([]Record, error)

	// Close the event log. It should not be re-opened after closing.
	Close() error

	// Name returns the event log's name.
	Name() string
}
