Types

type Level

type Level int

Level is a level of logging

const (
	// Error log level
	Error Level = iota
	// Warn log level
	Warn
	// Info log level
	Info
	// Debug log level
	Debug
)

func ParseLevel

func ParseLevel(lvl string) Level

ParseLevel parses the log level, returns Info level if not found
