Types

type Level

type Level int

Level defines the log level. Can be one of the following: * OFF * FATAL * ERROR * WARN * INFO * DEBUG * TRACE

const (
	// OFF disables logging
	OFF Level = iota
	// FATAL logs fatals
	FATAL
	// ERROR logs at least errors
	ERROR
	// WARN logs at least warnings
	WARN
	// INFO logs at least infos
	INFO
	// DEBUG logs at least debug output
	DEBUG
	// TRACE logs everything (verbose!)
	TRACE
)
