Functions

func TransformMap

func TransformMap[K comparable, E, V1, V2 any, IN ~map[K]V1, OUT ~map[K]V2](
	in IN,
	v1Len func(V1) int,
	appendV1ToSlice func(V1, []E) []E,
	elemToV2 func([]E) V2,
) OUT

TransformMap transforms map of type IN into a map of type OUT. The main point of this function is to optimize memory usage. It allocates a single slice for the elements in values of the map rather than a slice per key.
