    service_name: &str,
    trace_metadata: &HashMap<String, String, S>,
) -> String

Serialize spans to OTLP JSON Protobuf encoding.

trace_metadata entries are appended as additional resource attributes after service.name. The reserved key service.name in trace_metadata is skipped to avoid duplication.
