Module opentracing.span_context¶

SpanContext represents Span state that must propagate to descendant Span ‘s and across process boundaries.

SpanContext is logically divided into two pieces: the user-level “Baggage” (see Span.set_baggage_item and Span.get_baggage_item ) that propagates across Span boundaries and any tracer-implementation-specific fields that are needed to identify or otherwise contextualize the associated Span (e.g., a (trace_id, span_id, sampled) tuple).
