Level minLevel
The minimum log level to emit.
Definition: Logging.h:160
void logImpl(Level level, const std::string &subsystem, const std::string &msg, const std::map< std::string, std::any > *details) override
Subclasses must implement this method to log messages.
Definition: Logging.cpp:34
std::ostream & outStream
Everything except errors goes here.
Definition: Logging.h:163
std::ostream & errorStream
Just for errors.
Definition: Logging.h:165
StreamLogger(Level minLevel, std::ostream &out, std::ostream &error)
Create a stream logger that logs to the given output stream and error output stream.
Definition: Logging.h:149
A thread-safe logger which calls functions implemented by subclasses.
Definition: Logging.h:126
std::mutex mutex
Mutex to protect the stream from interleaved logging writes.
Definition: Logging.h:141
virtual void logImpl(Level level, const std::string &subsystem, const std::string &msg, const std::map< std::string, std::any > *details)=0
Subclasses must implement this method to log messages.
void log(Level level, const std::string &subsystem, const std::string &msg, const std::map< std::string, std::any > *details) override final
Grabs the lock and calls logImpl.

std::string toString(const std::any &a)
'Stringify' a std::any. This is used to log std::any values by some loggers.
