| // Thread safe logger (except for set_pattern(..), set_formatter(..) and set_error_handler()) |
| // Has name, log level, vector of std::shared sink pointers and formatter |
| // Upon each log write the logger: |
| // 1. Checks if its log level is enough to log the message |
| // 2. Format the message using the formatter function |
| // 3. Pass the formatted message to its sinks to performa the actual logging |
