Types

type GroupFilterHandler

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

GroupFilterHandler is a slog.Handler that filters log records based on the group associated with it. It only forwards log records to the underlying handler if the group of the log record is in the allow list.

Note this only handles groups created with the WithGroup() method. It does not handle groups created with slog.Group().

func New

func New(handler slog.Handler, allowGroups ...string) *GroupFilterHandler

New creates a new GroupFilterHandler that forwards log records to the provided handler if any groups associated with it is in the allow list. In case there are no allow groups, then all log records are forwarded.

func (*GroupFilterHandler) Enabled

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

Enabled implements slog.Handler.

func (*GroupFilterHandler) Handle

func (h *GroupFilterHandler) Handle(ctx context.Context, record slog.Record) error

Handle implements slog.Handler.

func (*GroupFilterHandler) WithAttrs

WithAttrs implements slog.Handler.

func (*GroupFilterHandler) WithGroup

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

WithGroup implements slog.Handler.
