public interface 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 Tracer-implementation-specific fields that are needed to identify or otherwise contextualize the associated Span instance (e.g., a <trace_id, span_id, sampled> tuple).
