Method: Datadog::Tracing::TraceDigest#trace_state_unknown_fields

Defined in:
lib/datadog/tracing/trace_digest.rb

#trace_state_unknown_fields ⇒ String (readonly)

From W3C “tracestate”‘s `dd=` entry, when keys are not recognized they are stored here long with their values. This allows later propagation to include those unknown fields, as they can represent future versions of the spec sending data through this service. This value ends in a trailing `;` to facilitate serialization.

Returns:

  • (String)
