+// that produces no telemetry and minimizes used computation resources.

+// Using this package to implement the OpenTelemetry Logs Bridge API will
+// effectively disable OpenTelemetry.
+//
+// This implementation can be embedded in other implementations of the
+// OpenTelemetry Logs Bridge API. Doing so will mean the implementation
+// defaults to no operation for methods it does not implement.
