type Set[K comparable] struct {
// contains filtered or unexported fields
}
func New
func New[K comparable]() Set[K]
New returns an empty hashset.

func (s Set[K]) Each(fn func(key K))
Each calls 'fn' on every item in the set in no particular order.
func (Set[K]) Has
func (s Set[K]) Has(val K) bool
Has returns true only if 'val' is in the set.
func (Set[K]) Put
func (s Set[K]) Put(val K)
Put adds 'val' to the set.
func (Set[K]) Remove
func (s Set[K]) Remove(val K)
