type Type 

type Type interface {
	// Connect attempts to establish a connection to the source, if unsuccessful
	// returns an error. If the attempt is successful (or not necessary) returns
	// nil.
	Connect() error

	// Acknowledge, if applicable to the source, should send acknowledgments for
	// (or commit) all unacknowledged (or uncommitted) messages that have thus
	// far been consumed. If the error is non-nil this means the message was
	// unsuccessfully propagated down the pipeline, in which case it is up to
	// the implementation to decide whether to simply retry uncommitted messages
	// that are buffered locally, or to send the error upstream.
	Acknowledge(err error) error

	// Read attempts to read a new message from the source.
	Read() (types.Message, error)

	types.Closable
