Functions

func ExecuteAll added in v4.1.0 

func ExecuteAll(ctx context.Context, procs []V1, msgs ...message.Batch) ([]message.Batch, error)

ExecuteAll attempts to execute a slice of processors to a message. Returns N resulting messages or a response. The response may indicate either a NoAck in the event of the message being buffered or an unrecoverable error.

func ExecuteCatchAll added in v4.1.0 

func ExecuteCatchAll(ctx context.Context, procs []V1, msgs ...message.Batch) ([]message.Batch, error)

func ExecuteTryAll added in v4.1.0 

func ExecuteTryAll(ctx context.Context, procs []V1, msgs ...message.Batch) ([]message.Batch, error)

ExecuteTryAll attempts to execute a slice of processors to messages, if a message has failed a processing step it is prevented from being sent to subsequent processors. Returns N resulting messages or a response. The response may indicate either a NoAck in the event of the message being buffered or an unrecoverable error.

func MarkErr 

func MarkErr(part *message.Part, span *tracing.Span, err error)
