Overview ¶
Package event provides a set of packages that cover the main concepts of telemetry in an implementation agnostic way.

Functions ¶
func Detach ¶
Detach returns a context without an associated span. This allows the creation of spans that are not children of the current span.
func Error ¶
Error takes a message and a label list and combines them into a single event before delivering them to the exporter. It captures the error in the delivered event.
func IsDetach ¶
IsDetach returns true if the event was built by the Detach function. It is intended to be used in exporters to identify the semantics of the event when deciding what to do with it.
func IsEnd ¶
IsEnd returns true if the event was built by the End function. It is intended to be used in exporters to identify the semantics of the event when deciding what to do with it.
func IsError ¶
IsError returns true if the event was built by the Error function. It is intended to be used in exporters to identify the semantics of the event when deciding what to do with it.
func IsLabel ¶
IsLabel returns true if the event was built by the Label function. It is intended to be used in exporters to identify the semantics of the event when deciding what to do with it.
func IsLog ¶
IsLog returns true if the event was built by the Log function. It is intended to be used in exporters to identify the semantics of the event when deciding what to do with it.
func IsMetric ¶
IsMetric returns true if the event was built by the Metric function. It is intended to be used in exporters to identify the semantics of the event when deciding what to do with it.
func IsStart ¶
IsStart returns true if the event was built by the Start function. It is intended to be used in exporters to identify the semantics of the event when deciding what to do with it.
func Log ¶
Log takes a message and a label list and combines them into a single event before delivering them to the exporter.
func SetExporter ¶
func SetExporter(e Exporter)
SetExporter sets the global exporter function that handles all events. The exporter is called synchronously from the event call site, so it should return quickly so as not to hold up user code.
