type Logger

type Logger interface {
	Sync() error

	// Verbosity == 0

	Errorw(msg string, keysAndValues ...interface{})

	// Verbosity >= 1
	Warn(args ...interface{})
	Warnf(template string, args ...interface{})
	Warnw(msg string, keysAndValues ...interface{})

	// Verbosity >= 2
	Info(args ...interface{})
	Infof(template string, args ...interface{})
	Infow(msg string, keysAndValues ...interface{})

	// Verbosity >= 3
	Debug(args ...interface{})
	Debugf(template string, args ...interface{})
	Debugw(msg string, keysAndValues ...interface{})
