Types

type Handler

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

func NewHandler

func NewHandler(out io.Writer, opts *HandlerOptions) *Handler

func (*Handler) Enabled

func (h *Handler) Enabled(_ context.Context, level slog.Level) bool

func (*Handler) Handle

func (h *Handler) Handle(_ context.Context, record slog.Record) error

func (*Handler) WithAttrs

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

func (*Handler) WithGroup

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

type HandlerOptions

type HandlerOptions struct {
	// Level reports the minimum record level that will be logged.
	// The handler discards records with lower levels.
	// If Level is nil, the handler assumes LevelInfo.
	// The handler calls Level.Level for each record processed;
	// to adjust the minimum level dynamically, use a LevelVar.
	Level slog.Leveler

	// ReplaceAttr is called to rewrite each non-group attribute before it is logged.
	// The attribute's value has been resolved (see [Value.Resolve]).
	// If ReplaceAttr returns a zero Attr, the attribute is discarded.
	//
	// The built-in attributes with keys "time", "level", "source", and "msg"
	// are passed to this function, except that time is omitted
	// if zero, and source is omitted if AddSource is false.
	//
	// The first argument is a list of currently open groups that contain the
	// Attr. It must not be retained or modified. ReplaceAttr is never called
	// for Group attributes, only their contents. For example, the attribute
	// list
	//
	//     Int("a", 1), Group("g", Int("b", 2)), Int("c", 3)
	//
	// results in consecutive calls to ReplaceAttr with the following arguments:
	//
	//     nil, Int("a", 1)
	//     []string{"g"}, Int("b", 2)
	//     nil, Int("c", 3)
	//
	// ReplaceAttr can be used to change the default keys of the built-in
	// attributes, convert types (for example, to replace a `time.Time` with the
	// integer seconds since the Unix epoch), sanitize personal information, or
	// remove attributes from the output.
	ReplaceAttr func(groups []string, a slog.Attr) slog.Attr
}

HandlerOptions are a subset of slog.HandlerOptions that are implemented for the UI handler.
