  raise 'Please invoke Datadog.configure at least once before calling this method' unless @propagation

  @propagation.extract(data)
end

.inject(digest, data) ⇒ Object

Inject distributed headers into the given request

Parameters:

• digest (Datadog::Tracing::TraceDigest) —

  the trace to inject
