Detailed Description

Functions related to logging.

To use the logger in your application, simply include this header, and call

#include <lagrange/Logger.h>
 
lagrange::logger().info("This is a message");
lagrange::logger().warning("Invalid value for x: {}", x);
 
// set logger verbosity
lagrange::logger().set_level(spdlog::level::debug);

The Lagrange logger is a plain spdlog logger, with a type-safe printf formatting syntax provided by fmt. For more details, please consult these libraries' respective documentations:
