Functions ¶

func ContextWithSpanFromContext ¶

func ContextWithSpanFromContext(ctx, ctx2 context.Context) context.Context

ContextWithSpanFromContext sets the tracing span of a context from other context if one is not already set. Alternative would be context.WithoutCancel() that would copy the context but reset ctx.Done

func FinishWithError ¶

func FinishWithError(span trace.Span, err error)

FinishWithError finalizes the span and sets the error if one is passed

func NewTransport ¶

func NewTransport(rt http.RoundTripper) http.RoundTripper

func StartSpan ¶

func StartSpan(ctx context.Context, operationName string, opts ...trace.SpanStartOption) (trace.Span, context.Context)

StartSpan starts a new span as a child of the span in context. If there is no span in context then this is a no-op.

Types ¶

type MultiSpan ¶

type MultiSpan struct {
	trace.Span
}

func NewMultiSpan ¶

func NewMultiSpan() *MultiSpan

func (*MultiSpan) Add ¶

func (ms *MultiSpan) Add(s trace.Span)
