void setLevel(LogLevel level)
Common includes and macros used throughout the library.
std::ostream & operator<<(std::ostream &os, LogLevel level)
Output LogLevel as a string.
LogLevel parseLogLevel(const std::string &s)
Parse LogLevel from a string.
LogLevel
Indicates the severity level of a log message.
@ FATAL
fatal (will be logged unconditionally)
@ TRACE
trace messages (most verbose)
@ INFO
informational messages
@ ERROR
serious error messages
