func CloseWatcher

func CloseWatcher(ctx context.Context, w http.ResponseWriter) (<-chan bool, <-chan bool)

CloseWatcher watches for CloseNotify and context timeout. It is best effort and may sometimes not close the channel relying on gc

func DurationToNanosBytes

func DurationToNanosBytes(r io.Reader) ([]byte, error)

DurationToNanosBytes transforms a json byte slice with Duration keys into Nanos

func DurationToNanosMap

func DurationToNanosMap(input map[string]interface{}) (map[string]interface{}, error)

DurationToNanosMap transforms keys with a Duration into Nanos

func Error

func Error(w http.ResponseWriter, err error, code int)

Error will serve an HTTP error

func IsInvalidParams

func IsInvalidParams(err error) bool

IsInvalidParams returns true if this is an invalid params error

func NewSearchHandler

func NewSearchHandler(storage storage.Storage) http.Handler

NewSearchHandler returns a new instance of handler

func WriteJSONResponse

func WriteJSONResponse(w http.ResponseWriter, data interface{}, logger *zap.Logger)

WriteJSONResponse writes generic data to the ResponseWriter

func WriteProtoMsgJSONResponse

func WriteProtoMsgJSONResponse(w http.ResponseWriter, data proto.Message, logger *zap.Logger)
