Types

type Set

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

Set is a set of elements based on hash table

func Diff

func Diff(sets ...*Set) *Set

Diff subtracts two sets

func Intersect

func Intersect(sets ...*Set) *Set

Intersect intersects two sets

func Make

func Make(members ...string) *Set

Make creates a new set

func Union

func Union(sets ...*Set) *Set

Union adds two sets

func (*Set) Add

func (set *Set) Add(val string) int

Add adds member into set

func (*Set) ForEach

func (set *Set) ForEach(consumer func(member string) bool)

ForEach visits each member in the set

func (*Set) Has

func (set *Set) Has(val string) bool

Has returns true if the val exists in the set

func (*Set) Len

func (set *Set) Len() int

Len returns number of members in the set
