Functions

func ExecutionAttributes

func ExecutionAttributes(requestID string, req execute.Request) []attribute.KeyValue

func SpanAttributes

func SpanAttributes(attributes []attribute.KeyValue) []trace.SpanStartOption

func TraceContext

func TraceContext(ctx context.Context, t TraceInfo) context.Context

TraceContext injects the trace information into passed context.

func TraceContextFromMessage

func TraceContextFromMessage(ctx context.Context, payload []byte) (context.Context, error)

TraceContextFromMessage will try to extract TraceInfo from the JSON message.

Types

type TraceInfo

type TraceInfo struct {
	Carrier propagation.MapCarrier
}

func GetTraceInfo

func GetTraceInfo(ctx context.Context) TraceInfo

GetTraceInfo extracts tracing information from the context.

func GetTraceInfoWithPropagator
