Functions

func RegisterTracing

func RegisterTracing(opts *config.TracingOptions) (trace.Exporter, error)

RegisterTracing creates a new trace exporter from TracingOptions.

func StartSpan

func StartSpan(ctx context.Context, name string, o ...trace.StartOption) (context.Context, *trace.Span)

StartSpan starts a new child span of the current span in the context. If there is no span in the context, creates a new trace and span.

Returned context contains the newly created span. You can use it to propagate the returned span in process.

func UnregisterTracing

func UnregisterTracing(exporter trace.Exporter)

UnregisterTracing unregisters a trace exporter.
