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.
Synopsis
Declared in <absl/log/structured.h>
/* implementation-defined */::AsLiteralImpl
LogAsLiteral(std::string_view s);Description
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); }
LogAsLiteral should only be used as a streaming operand and not, for example, as a local variable initializer.
Return Value
An object that streams s as a literal field.
