Constants

const (
	// DefaultMessagesPrintingFrequency describes the default frequency at which messages are printed
	DefaultMessagesPrintingFrequency = 100 * time.Millisecond

	// DefaultMessageFetchingBackoff describes the fixed backoff duration before more messages are fetched.
	DefaultMessageFetchingBackoff = 10 * time.Millisecond

)

Functions

func FormatMessage

func FormatMessage(msg IMessage) (s string, err error)

FormatMessage formats a job message.

func NewMockNotificationFeedPage

func NewMockNotificationFeedPage(ctx context.Context, hasNext, hasFuture bool) (f *client.NotificationFeed, err error)

NewMockNotificationFeedPage generates a mock message page for testing

func NewMockNotificationFeedPaginator

func NewMockNotificationFeedPaginator(ctx context.Context) (pagination.IPaginatorAndPageFetcher, error)

NewMockNotificationFeedPaginator generates a mock message paginator for testing

func NewMockNotificationFeedStreamPaginator

func NewMockNotificationFeedStreamPaginator(ctx context.Context) (pagination.IStreamPaginatorAndPageFetcher, error)

Types

type IMessage

type IMessage interface {
	// GetCtimeOk returns the creation time
	GetCtimeOk() (*time.Time, bool)
	// GetMessageOk returns the message string
	GetMessageOk() (*string, bool)
	// GetSeverityOk returns the message severity
	GetSeverityOk() (*string, bool)
	// GetSourceOk returns the message source.
	GetSourceOk() (*string, bool)
}

IMessage defines a generic service message.

type IMessageLogger

type IMessageLogger interface {
	logs.Loggers
	LogMessage(msg IMessage)
	LogEmptyMessageError()
	LogMarshallingError(rawMessage *any)
	LogMessagesCollection(ctx context.Context, messagePaginator pagination.IGenericPaginator) error
}

IMessageLogger defines a logger dedicated to printing service messages.

func NewBasicAsynchronousMessageLogger

func NewBasicAsynchronousMessageLogger(ctx context.Context, rawLogger logging.ILogger) (IMessageLogger, error)

NewBasicAsynchronousMessageLogger creates an asynchronous logger for messages which prints them as they come.

func NewBasicSynchronousMessageLogger

func NewBasicSynchronousMessageLogger(ctx context.Context, rawLogger logging.ILogger) (IMessageLogger, error)

NewBasicSynchronousMessageLogger creates a synchronous logger for messages which prints them as they come.

func NewPeriodicAsynchronousMessageLogger

func NewPeriodicAsynchronousMessageLogger(ctx context.Context, rawLogger logging.ILogger, printPeriod time.Duration) (IMessageLogger, error)

NewPeriodicAsynchronousMessageLogger creates an asynchronous logger for messages which prints them at regular intervals.

func NewPeriodicSynchronousMessageLogger
