type HashSet struct { set *hashset.Set }

func NewHashSet() *HashSet { var result HashSet result.set = hashset.New() return &result }

// If call Add("abc"), it will crash and output "unhashable type []interface", why? func (s *HashSet) Add(items ...interface{}) { s.set.Add(items) }

Thank you.

There is no problem with gods. The reason cause this problem is the way you use ...interface{} try following:

func (s *HashSet) Add(items ...interface{}) {
		s.set.Add(items...)
}

func (s *HashSet) Add(items ...interface{}) {
	for _,item := range items {
		s.set.Add(item)
	}
}

There is no problem with `gods`. The reason cause this problem is the way you use ...interface{} try following: ``` func (s *HashSet) Add(items ...interface{}) { s.set.Add(items...) } ``` or ``` func (s *HashSet) Add(items ...interface{}) { for _,item := range items { s.set.Add(item) } } ```
