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 opentracing.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 ...opentracing.StartSpanOption) (opentracing.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. The difference from opentracing.StartSpanFromContext is that this method does not depend on global tracer.

Types ¶

type MultiSpan ¶

type MultiSpan struct {
	opentracing.Span
}

func NewMultiSpan ¶

func NewMultiSpan() *MultiSpan

func (*MultiSpan) Add ¶

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

type Transport ¶

type Transport struct {
	http.RoundTripper
}

func (*Transport) RoundTrip ¶

func (t *Transport) RoundTrip(req *http.Request) (*http.Response, error)
