Method DoubleAck

jetstream/message.go:360–362

DoubleAck acknowledges a message and waits for ack reply from the server. While it impacts performance, it is useful for scenarios where message loss is not acceptable.

(ctx context.Context)

// While it impacts performance, it is useful for scenarios where
// message loss is not acceptable.
func (m *jetStreamMsg) DoubleAck(ctx context.Context) error {
	return m.ackReply(ctx, ackAck, true, ackOpts{})
}

// Nak negatively acknowledges a message. This tells the server to
// redeliver the message.
