panic: T for Rta algo - Githubissues

Hello, i am using go-callvis with the rta algorithm. However i got a panic with it:

$ go-callvis  -algo rta .
panic: T

goroutine 1 [running]:

it seems that the panic occurs on following code:

type Iter[T any] interface {
    // Next returns next N items of iterator when it is not empty.
    // When iterator is empty, nil is returned.
    // When n = [ALL] or n is greater than number of remaining elements,
    // all remaining are returned.
    //
    // The returned slice is owned by caller. So implementer should return a
    // newly allocated slice if needed.
    //
    // Passing in a negative n (except [ALL]) is undefined behavior.
    Next(n int) []T
}

Does the RTA algorithm not support generics?
