Types

type LineHandler

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

LineHandler is a slog.Handler that writes log events one per line in an easy-to-read format:

time level message label1=value1 label2=value2 ...

func NewLineHandler

func NewLineHandler(w io.Writer) *LineHandler

func (*LineHandler) Enabled

func (h *LineHandler) Enabled(ctx context.Context, level slog.Level) bool

func (*LineHandler) Handle

func (h *LineHandler) Handle(ctx context.Context, r slog.Record) error

func (*LineHandler) WithAttrs

func (h *LineHandler) WithAttrs(as []slog.Attr) slog.Handler

func (*LineHandler) WithGroup

func (h *LineHandler) WithGroup(name string) slog.Handler
