CloudTraceFormatter

This format using a human readable string encoding to propagate SpanContext.

GrpcMetadataPropagator

HttpHeaderPropagator

TraceContextFormatter

This format using a human readable string encoding to propagate SpanContext.

FormatterInterface

This interface lets us define serialization strategies for SpanContext.

PropagatorInterface

This interface lets us define separate SpanContext Propagator formats. This interface is responsible for parsing and propagating the SpanContext to upstream and downstream requests.
