Functions

func SetUnzip

func SetUnzip[T, T2 any](t two.Tuple[T, T2]) (Set[T], Set[T2])

SetUnzip separates the values of t into two Sets.

func SetZip

func SetZip[T, T2 any](s Set[T], s2 Set[T2]) two.Tuple[T, T2]

SetZip combines the values of s and s2 into a two.Tuple.

Types

type Set

type Set[E any] map[unit.Type]E

Set contains at most one element.

It works like a map. Use the key unit.Unit to access the element:

v, ok := s[unit.Unit]

func SetOf

func SetOf[E any](v E) Set[E]

SetOf creates a Set of v.

func (Set[E]) String

func (s Set[E]) String() string

String returns the Set formatted as a string.
