Warn Struct Reference

Detailed Description

When constructed, logs a message (at "warn" severity); the destructor is guaranteed to be trivial.

This is useful for declaring an instance of this class as a function-static global, so that a warning is logged the first time the program encounters some code, but does not repeat the warning on subsequent encounters within the same process.

For example:

double* SanityCheck(double* data) {
  if (!data) {
    static const logging::Warn log_once("Bad data!");
    return alternative_data();
  return data;

#include <src/maliput/drake/common/text_logging.h>
