All Implemented Interfaces:

io.opentracing.SpanContext
```
public class DDSpanContext
 implements SpanContext
                    
```
SpanContext represents Span state that must propagate to descendant Spans and across process boundaries.
SpanContext is logically divided into two pieces: (1) the user-level "Baggage" that propagates across Span boundaries and (2) any Datadog fields that are needed to identify or contextualize the associated Span instance
