	// Using dash character with UUIDv4 string
	g := goid.NewUuidV4Generator(true)

	// Generate ID
	id := g.Generate()

	fmt.Println(id.Nil())    // Returns boolean whether id is nil or not
	fmt.Println(id.String()) // Converts ID to string
	fmt.Println(id)

	target := g.Generate()
	ids := goid.NewIDs(
		target,
		g.Generate(),
		g.Generate(),
	)
	fmt.Println(ids)

	g2 := goid.NewUuidV4Generator(false)
	fmt.Println(g2.Generate())

Namespace Generator

Default delimiter

g := goid.NewNamespaceGenerator("com")
id := g.Generate("github", "bearchit", "goid")
// id = com.github.bearchit.goid

Custom delimiter

g := goid.NewNamespaceGenerator("com", goid.WithDelimiter("-"))
id := g.Generate("github", "bearchit", "goid")
// id = com-github.bearchit-goid
