Functions ¶

func NewChildSpan ¶

func NewChildSpan(ctx context.Context, tr *tracing.Tracer,
	spanName string) (context.Context, trace.Span)

NewChildSpan returns the context with a new Span situated as the child of the previous span

func PrepareRequest ¶

func PrepareRequest(r *http.Request, tr *tracing.Tracer) (*http.Request, trace.Span)

PrepareRequest extracts trace information from the headers of the incoming request. It returns a pointer to the incoming request with the request context updated to include all span and tracing info. It also returns a span with the name "Request" that is meant to be a parent span for all child spans of this request.

func SetAttributes ¶

func SetAttributes(tr *tracing.Tracer, span trace.Span, kvs ...label.KeyValue)

SetAttributes safely sets attributes on a span, unless they are in the omit list
