Functions

func Handler

func Handler(next http.Handler, operationName string) http.Handler

Handler wraps next with OpenTelemetry instrumentation: a root span is created for each request (or the incoming trace context is extracted from W3C headers), and the span is named after operationName. Use after metry.Init so the global TracerProvider and propagators are set.
