Types

type Logger

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

func NewLogger

func NewLogger(out io.Writer, prefix string, flag int) *Logger

New creates a new Logger. The out variable sets the destination to which log data will be written. The prefix appears at the beginning of each generated log line. The flag argument defines the logging properties.

func (*Logger) Output

func (l *Logger) Output(level int, s string) error

Output writes the output for a logging event. The string s contains the text to print after the prefix specified by the flags of the Logger. A newline is appended if the last character of s is not already a newline. Calldepth is used to recover the PC and is provided for generality, although at the moment on all pre-defined paths it will be 2.

func (*Logger) SetFlags

func (l *Logger) SetFlags(flag int)

SetFlags sets the output flags for the logger.

func (*Logger) SetPrefix

func (l *Logger) SetPrefix(prefix string)

SetPrefix sets the output prefix for the logger.

func (*Logger) SetWriter

func (l *Logger) SetWriter(writer io.Writer)
