logging Namespace Reference

Namespace containing all global type/structs that will be used project wide for logging. More...

Classes
class	LoggingFilter
	This class serves as a container class for handling log filtering of loggers. This must be used if you want each handler to have a different logging level since adding multiple handlers to the same logger will apply the loggers logging level to each handler. More...
class	MRDTConsoleSink
	A custom console sink for logging messages with specific formatting and timestamping. This class extends quill::ConsoleSink and provides the capability to format log messages using a specified pattern and time format, allowing for customizable and colorized console outputs. More...
class	MRDTRotatingFileSink
	A custom rotating file sink that formats and logs messages to a file with automatic rotation based on file size or time interval. This class extends quill::RotatingFileSink and provides the ability to format log messages using a pattern and time format, ensuring that logs are written to a rotating file system. More...

Functions
void	InitializeLoggers (std::string szLoggingOutputPath, std::string szProgramTimeLogsDir)
	Logger Initializer - Sets Up all the logging handlers required for having the above loggers.

   Priority > Level     > Description
   Level 1  > TRACE_L3  > Unused
   Level 2  > TRACE_L2  > Unused
   Level 3  > TRACE_L1  > Unused
   Level 4  > DEBUG     > Details that would only be useful in a debug environment
   Level 5  > INFO      > State Changes, RoveComm Updates GPS/IMU/Autonomy, etc
   Level 6  > WARNING   > Something unexpected happened - application could potentially error soon.
   Level 7  > ERROR     > Something went wrong - application could potentially have critical error soon.
   Level 8  > CRITICAL  > Something went very wrong - application will exit after logging is sent.

   Note: At testing sessions we will have "DEBUG" Logging set as the level that is being outputted.
         However, at competition and when using "RELEASE" code we will be using "INFO" Logging. When
         a logging level is set, we only receive logging messages that are that level or higher
         priority.

   Example: When INFO is set, we only receive: INFO, WARNING, ERROR, CRITICAL
            When DEBUG is set, we only receive: DEBUG, INFO, WARNING, ERROR, CRITICAL
