Module trace_fields 

The field catalogue of span schema rustev.otel/1 (spec 028, 3.5 and 3.6): the closed table of exportable field names and each one’s class rule. A name outside it is never exported, and a reader withholds it.

Span attributes are named as in 3.5.4. An event attribute is catalogued as <event name>.<attribute key> (rustev.input.source for the source attribute of a rustev.input event), and a metric attribute that is no span attribute as <instrument>.<attribute key>. Two names are templates whose last segment is instance-specific: rustev.outcome.param.<name> (the plan’s parameter name) and rustev.exchange.extra.<key> (a key the provider supplies).
