#include <userver/logging/log_helper.hpp>

Detailed Description

Stream-like tskv-formatted log message builder.

Users can add LogHelper& operator<<(LogHelper&, ) overloads to use a faster localeless logging, rather than outputting data through the ostream operator.

Constructor & Destructor Documentation

◆ LogHelper() [1/2]

logging::LogHelper::LogHelper	(	LoggerRef	logger,
		Level	level,
		const utils::impl::SourceLocation &	location = utils::impl::SourceLocation::Current() )

noexcept

Constructs LogHelper with span logging.

Parameters

logger	to log to
level	message log level
location	source location that will be written to logs

◆ LogHelper() [2/2]

logging::LogHelper::LogHelper	(	const LoggerPtr &	logger,
		Level	level,
		const utils::impl::SourceLocation &	location = utils::impl::SourceLocation::Current() )

noexcept

Constructs LogHelper with span logging.

Parameters

logger	to log to (logging to nullptr does not output messages)
level	message log level
location	source location that will be written to logs
