genericset provides a simple map-based implementation of generic set.
It uses sync.RWMutex to keep consistency of data.
go get github.com/rutaka-n/genericsetimport (
gs "github.com/rutaka-n/genericset"
)
func main() {
s1 := gs.New[int]()
s2 := gs.New[int]()
s1.Add(1,2,3)
s2.Add(3,4,5)
s1.Intersection(&s2) // [3]
s1.Union(&s2) // [1,2,3,4,5]
s1.IsEmpty() // false
s1.Size() // 3
s1.IsSubset(&s2) // false
// etc
