)

String constants representing each processor type.

Variables

var Constructors = map[string]TypeSpec{}

Constructors is a map of all processor types with their specs.

var FailFlagKey = types.FailFlagKey

FailFlagKey is a metadata key used for flagging processor errors in Benthos. If a message part has any non-empty value for this metadata key then it will be interpretted as having failed a processor step somewhere in the pipeline.

func Block Uses

func Block(typeStr, reason string)

Block replaces the constructor of a Benthos processor such that its construction will always return an error. This is useful for building strict pipelines where certain processors should not be available. NOTE: This does not remove the processor from the configuration spec, and normalisation will still work the same for blocked processors.

EXPERIMENTAL: This function is experimental and therefore subject to change outside of major version releases.

func ClearFail Uses

func ClearFail(part types.Part)

ClearFail removes any existing failure flags from a message part.

func Descriptions Uses

func Descriptions() string

Descriptions returns a formatted string of collated descriptions of each type.

func DocumentPlugin Uses

func ExecuteAll Uses

func ExecuteCatchAll Uses

func ExecuteCatchAll(procs []types.Processor, msgs ...types.Message) ([]types.Message, types.Response)

func ExecuteTryAll Uses
