func Map[In any, Out any](
	in *In,
	fn func(*In) Out,
) Out

Map maps a non-nil input; nil returns the output zero value without calling fn.

func MapGroups[In any, Out any](
	m map[string][]*In,
	fn Func[*In, Out],
) map[string][]Out

MapGroups maps each named group while preserving its key and item order.

func MapSlice[In any, Out any](
	items []*In,
	fn Func[*In, Out],
) []Out

MapSlice preserves order and maps nil entries to output zero values.

type Func[In any, Out any] func(In) Out

Func maps one input to an output.
