// WARNING: Pigweed strongly recommends sticking to printf-style logging instead
// of C++ stream-style Google Log logging unless absolutely necessary. These
// macros are only provided for compatibility with non-embedded code. See
// https://pigweed.dev/pw_log/ for more details.

// A subset of the streaming Google logging (glog) macros are supported:
// - LOG(glog_level)
// - LOG_IF(glog_level, condition)
//
// The supported glog levels are DEBUG, INFO, WARNING, ERROR, FATAL & DFATAL
//
// This means the following are NOT supported:
// - glog level DFATAL
// - {D,P,SYS}LOG*
// - {,D}VLOG*
// - {,D}CHECK*
// - LOG_EVERY_*, LOG_EVERY_*, LOG_IF_EVERY_*, LOG_FIRST_N
