Struct Logger

type LogFunction func() []interface{}

type Logger struct {
	// The logs are `io.Copy`'d to this in a mutex. It's common to set this to a
	// file, or leave it default which is `os.Stderr`. You can also set this to
	// something more adventurous, such as logging to Kafka.
	Out io.Writer
	// Hooks for the logger instance. These allow firing events based on logging
	// levels and log entries. For example, to send errors to an error tracking
	// service, log to StatsD or dump the core on fatal errors.
	Hooks LevelHooks
	// All log entries pass through the formatter before logged to Out. The
	// included formatters are `TextFormatter` and `JSONFormatter` for which
	// TextFormatter is the default. In development (when a TTY is attached) it
	// logs with colors, but to a file it wouldn't. You can easily implement your
	// own that implements the `Formatter` interface, see the `README` or included
	// formatters for examples.
	Formatter Formatter

	// Flag for whether to log caller info (off by default)
	ReportCaller bool

	// The logging level the logger should log at. This is typically (and defaults
	// to) `logrus.Info`, which allows Info(), Warn(), Error() and Fatal() to be
	// logged.
	Level Level
	// Used to sync writing to the log. Locking is enabled by Default
	mu MutexWrap
	// Reusable empty entry
	entryPool sync.Pool
	// Function to exit the application, defaults to `os.Exit()`
	ExitFunc exitFunc
	// The buffer pool used to format the log. If it is nil, the default global
	// buffer pool will be used.
