Types

type Level

type Level int8

A Level is a logging priority. Higher levels are more important.

const (
	// DebugLevel logs are typically voluminous, and are usually disabled in
	// production.
	DebugLevel Level = iota - 1
	// InfoLevel is the default logging priority.
	InfoLevel
	// WarnLevel logs are more important than Info, but don't need individual
	// human review.
	WarnLevel
	// ErrorLevel logs are high-priority. If an application is running smoothly,
	// it shouldn't generate any error-level logs.
	ErrorLevel
	// PanicLevel logs are particularly important errors. In development the
	// logger panics after writing the message.
	PanicLevel
	// FatalLevel logs a message, then calls os.Exit(1).
	FatalLevel
)
