Functions ¶
func ContextWithSpanFromContext ¶
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 ¶ added in v0.7.0
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)
