)

Types

type DistributedTracingExtension

type DistributedTracingExtension struct {
	TraceParent string `json:"traceparent"`
	TraceState  string `json:"tracestate"`
}

DistributedTracingExtension represents the extension for cloudevents context

func FromSpanContext

func FromSpanContext(sc trace.SpanContext) DistributedTracingExtension

FromSpanContext populates DistributedTracingExtension from a SpanContext.

func GetDistributedTracingExtension

func GetDistributedTracingExtension(event cloudevents.Event) (DistributedTracingExtension, bool)

func (DistributedTracingExtension) AddTracingAttributes

func (d DistributedTracingExtension) AddTracingAttributes(ec EventTracer) error

AddTracingAttributes adds the tracing attributes traceparent and tracestate to the cloudevents context

func (DistributedTracingExtension) StartChildSpan

func (d DistributedTracingExtension) StartChildSpan(ctx context.Context, name string, opts ...trace.StartOption) (context.Context, *trace.Span)

func (DistributedTracingExtension) ToSpanContext

func (d DistributedTracingExtension) ToSpanContext() (trace.SpanContext, error)

ToSpanContext creates a SpanContext from a DistributedTracingExtension instance.

type EventTracer

type EventTracer interface {
	SetExtension(k string, v interface{}) error
}

EventTracer interface allows setting extension for cloudevents context.
