Detailed Description

Serialization/deserialization of Zipkin zipkin.proto messages.

Implements the subset of zipkin.proto3 required for POST /api/v2/spans. Field numbers match openzipkin/zipkin-api zipkin.proto: Span: trace_id=1, parent_id=2, id=3, kind=4, name=5, timestamp=6, duration=7, local_endpoint=8, remote_endpoint=9, annotations=10, tags=11, debug=12, shared=13 Endpoint: service_name=1, ipv4=2, ipv6=3, port=4 Annotation: timestamp=1, value=2 ListOfSpans: spans=1

Note: timestamp is encoded as fixed64 per spec; duration is varint uint64.
