Functions

func DeleteAllStreams

func DeleteAllStreams(js natsclient.JetStreamContext, cfg *config.JetStream)

func InputRoomEventSubj

func InputRoomEventSubj(roomID string) string

func JetStreamConsumer

func JetStreamConsumer(
	ctx context.Context, js nats.JetStreamContext, subj, durable string, batch int,
	f func(ctx context.Context, msgs []*nats.Msg) bool,
	opts ...nats.SubOpt,
) error

JetStreamConsumer starts a durable consumer on the given subject with the given durable name. The function will be called when one or more messages is available, up to the maximum batch size specified. If the batch is set to 1 then messages will be delivered one at a time. If the function is called, the messages array is guaranteed to be at least 1 in size. Any provided NATS options will be passed through to the pull subscriber creation. The consumer will continue to run until the context expires, at which point it will stop.

func Tokenise

func Tokenise(str string) string

Types

type NATSInstance

type NATSInstance struct {
	*natsserver.Server
}

func (*NATSInstance) Prepare

func (s *NATSInstance) Prepare(process *process.ProcessContext, cfg *config.JetStream) (natsclient.JetStreamContext, *natsclient.Conn)
