Types

type JSONLogger

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

func NewJSONLogger

func NewJSONLogger(w io.Writer) *JSONLogger

NewJSONLogger creates a new JSONLogger which generates valid JSON ouputs and includes the same unique id in each log line generated through this logger.

func (*JSONLogger) Logln

func (j *JSONLogger) Logln(msg string, fields map[string]string)

func (*JSONLogger) Write

func (j *JSONLogger) Write(p []byte) (int, error)

Write implements the io.Writer interface. The input is expected to be log lines separated by newlines. If the log line is already valid JSON, the logger simply adds the id field. If the log line is not valid JSON, then the log line is wrapped in a JSON.

type PrefixWriter

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

PrefixWriter wraps an io.Writer to automatically add a prefix at the beginning of every line.

func NewPrefixWriter

func NewPrefixWriter(w io.Writer) *PrefixWriter

NewPrefixWriter creates a PrefixWriter.

func (*PrefixWriter) SetPrefix

func (w *PrefixWriter) SetPrefix(prefix []byte)

SetPrefix sets the prefix.

func (*PrefixWriter) Write

func (w *PrefixWriter) Write(p []byte) (n int, err error)
