Set seed does not appear to be working, anyone know why?

[Atticus Sebastiani]

use noise::{OpenSimplex, Seedable, NoiseFn};

fn main() {
  let g:OpenSimplex = OpenSimplex::new();
  println!("{:?}",g.seed());
  g.set_seed(128941);
  println!("{:?}",g.seed());
}

It should print whatever the default seed is then print the new seed 128941 but instead, it just prints 0 both times. I've tried messing around with different trait imports among other things but nothing changes. I don't know if this is a bug or if I'm just doing something wrong.

I didn't realize that set_seed() returns the noise.
Fbm::new().set_seed(seed)
This worked.
