Types

type Level

type Level int8

Level type represents the severity level for an entry log

const (
	LevelInfo Level = iota
	LevelError
	LevelFatal
	LevelOff
)

Initialize constants to represent various severity levels

func (Level) String

func (l Level) String() string

Create and return a human-friendly message for each severity level

type Logger

type Logger struct {
	// contains filtered or unexported fields
}

Logger type holds the output destination that the log entries will be written to, the minimum severity level that log entries will be written for, plus a mutex for coordinating the writes.

func New

func New(out io.Writer, minLevel Level) *Logger

New() returns a new Logger instance which writes log entries at or above a minimum severity level to a specific output destination.

func (*Logger) PrintError

func (l *Logger) PrintError(err error, props map[string]string)

func (*Logger) PrintFatal

func (l *Logger) PrintFatal(err error, props map[string]string)

func (*Logger) PrintInfo

func (l *Logger) PrintInfo(message string, props map[string]string)

func (*Logger) Write

func (l *Logger) Write(message []byte) (n int, err error)

Implement the Write method on the Logger type for it to satisfy the io.Writer interface
