CloudTrace Propagator
CloudTrace is a propagator that supports the specification for the header "x-cloud-trace-context" used for trace context propagation across service boundaries. (https://cloud.google.com/trace/docs/setup#force-trace). OpenTelemetry PHP CloudTrace Propagator Extension provides option to use it bi-directionally or one-way. One-way does not inject the header for downstream consumption, it only processes the incoming headers and returns the correct span context. It only attaches to existing X-Cloud-Trace-Context traces and does not create downstream ones.
For one-way CloudTrace:
CloudTracePropagator::getOneWayInstance()
For bi-directional CloudTrace:
CloudTracePropagator::getInstance()
