Span::$trace_id

A unique identifier for a trace. All spans from the same trace share the same `trace_id`. The ID is a 16-byte array. An ID with all zeroes OR of length other than 16 bytes is considered invalid (empty string in OTLP/JSON is zero-length and thus is also invalid). This field is required.

Generated from protobuf field <code>bytes trace_id = 1;</code>

Type: trace_id
