-// A NoopTracer is a trivial, minimum overhead implementation of Tracer
-// for which all operations are no-ops.
-//
-// The primary use of this implementation is in libraries, such as RPC
-// frameworks, that make tracing an optional feature controlled by the
-// end user. A no-op implementation allows said libraries to use it
-// as the default Tracer and to write instrumentation that does
-// not need to keep checking if the tracer instance is nil.
-//
-// For the same reason, the NoopTracer is the default "global" tracer
-// (see Tracer::Global and Tracer::InitGlobal functions).
-//
-// WARNING: NoopTracer does not support baggage propagation.
