Overview

Package input defines consumers for aggregating data from a variety of sources. All consumer types must implement interface input.Type.

If the source of an input consumer supports acknowledgements then the implementation of the input will wait for each message to reach a permanent destination before acknowledging it.

Functions

func Descriptions() string

Descriptions returns a formatted string of descriptions for each type.

func DocumentPlugin 

func DocumentPlugin(
	typeString, description string,
	configSanitiser PluginConfigSanitiser,
)

DocumentPlugin adds a description and an optional configuration sanitiser function to the definition of a registered plugin. This improves the documentation generated by PluginDescriptions.

func PluginCount 

func PluginCount() int

RegisterPlugin registers a plugin by a unique name so that it can be constructed similar to regular inputs. If configuration is not needed for this plugin then configConstructor can be nil. A constructor for the plugin itself must be provided.

func SanitiseConfig 

func SanitiseConfig(conf Config) (interface{}, error)
