func Fatal(v ...any)

Fatal is equivalent to glob.Print() followed by a call to os.Exit(1).

func Fatalf

func Fatalf(format string, v ...any)

Fatalf is equivalent to glob.Printf() followed by a call to os.Exit(1).

func Fatalln

func Fatalln(v ...any)

Fatalln is equivalent to glob.Println() followed by a call to os.Exit(1).

func Flags

func Flags() int

Flags returns the output flags for the logger.

func Output

func Output(calldepth int, s string) error

func SetOutput

func SetOutput(w io.Writer)

SetOutput sets the output destination for the standard logger.

func SetPrefix

func SetPrefix(prefix string)

SetPrefix sets the output prefix for the logger.

func Writer

func Writer() io.Writer
