)

func main() {
	// Initialize a Cassandra adapter and use it in a Casbin enforcer:
	a := cassandraadapter.NewAdapter("127.0.0.1") // Your Cassandra hosts. 
	e := casbin.NewEnforcer("examples/rbac_model.conf", a)
	
	// Load the policy from DB.
	e.LoadPolicy()
	
	// Check the permission.
	e.Enforce("alice", "data1", "read")
	
	// Modify the policy.
	// e.AddPolicy(...)
