This repo contains a conformance runner that writes a span context to a client library via stdout and reads the response from stdin.
OpenTracing defines the TextMap as "a platform-idiomatic map from (unicode) string to string". LightStep implements the TextMap by encoding the SpanContext into a map of string to string. Given a LightStep SpanContext, we expect the following fields in the map
ot-tracer-spanid contains a uint encoded as base16 characters.
ot-tracer-traceid contains a uint encoded as bas16 characters.
ot-tracer-sampled is a boolean encoded as a string with the values true or false
Baggage items are key value pairs. All baggage keys are prefixed
with ot-baggage- and the corresponding value is the raw string.
