// This header declares APIs supporting structured logging, allowing log
// statements to be more easily parsed, especially by automated processes.
//
// When structured logging is in use, data streamed into a `LOG` statement are
// encoded as `Value` fields in a `logging.proto.Event` protocol buffer message.
// The individual data are exposed programmatically to `LogSink`s and to the
// user via some log reading tools which are able to query the structured data
// more usefully than would be possible if each message was a single opaque
// string.  These helpers allow user code to add additional structure to the
// data they stream.

// LogAsLiteral()
//
// Annotates its argument as a string literal so that structured logging
// captures it as a `literal` field instead of a `str` field (the default).
// This does not affect the text representation, only the structure.
//
// Streaming `LogAsLiteral(s)` into a `std::ostream` behaves just like streaming
// `s` directly.
//
// Using `LogAsLiteral()` is occasionally appropriate and useful when proxying
// data logged from another system or another language.  For example:
//
//   void Logger::LogString(absl::string_view str, absl::LogSeverity severity,
//                          const char *file, int line) {
//     LOG(LEVEL(severity)).AtLocation(file, line) << str;
//   }
//   void Logger::LogStringLiteral(absl::string_view str,
//                                 absl::LogSeverity severity, const char *file,
//                                 int line) {
//     LOG(LEVEL(severity)).AtLocation(file, line) << absl::LogAsLiteral(str);
//   }
