	Tracer opentracing.Tracer

	// SpanContextKey is the context key used for internal span tracking (not to
	// be confused with the context key OpenTracing uses internally). If not set,
	// this defaults to an internal key (recommended).
	SpanContextKey interface{}

	// HeaderKey is the Temporal header field key used to serialize spans. If
	// empty, this defaults to the one used by all SDKs (recommended).
	HeaderKey string

	// SpanStarter is a callback to create spans. If not set, this creates normal
	// OpenTracing spans calling Tracer.StartSpan.
