Types

type FuncLogger

type FuncLogger interface {
	Logger

	// Func allows for a logger callback, that can be optionally disabled based on the log level.
	// This way, expensive logging operations can be avoided if the log level is too low by putting them
	// inside the function.
	Func(func(Logger))
