| amnicolist | Hi flakes, I'm new to nixos/flakes and this chat. I have a question about flake-parts and overlays. I hope its okay to ask here.
I'm trying to get the [rust-overlay](https://github.com/oxalica/rust-overlay

I'm trying to get the [rust-overlay](https://github.com/oxalica/rust-overlay) working with an existing repo that I forked. However, I can't figure out how to get access to the rust-bin set once I follow the https://flake.parts/overlays documentation

 Charles | Would you be amenable to an alternative that doesn't involve overlays | 02:43:36 |

 @antifuchs:asf.computer | amnicolist: you're following the "consuming an overlay" section? | 17:47:28 |
| @antifuchs:asf.computer | that will define the "pkgs" attribute available in the perSystem closure's arguments as the overlaid version, but you then also have to go and use that pkgs attribute to define the system / home-manager configuration... that's typically what trips me up | 17:49:43 |
| @antifuchs:asf.computer | but anyway, how are you planning to use the overlay? (: | 17:50:28 |

amnicolist: you're following the "consuming an overlay" section? Yes, I saw the stuff about consuming the overlay. That explained how to get the rust-overlay into the pkgs. I think I kind-of get that. The problem came when I wanted to actually install the package. I want to have multiple rust tool chains installed, nightly for some things etc. My understanding fell down when I tried to call something like
home.packages = with pkgs; [
rust-bin.stable.latest.default
];

Nixos would complain that it can't find rust-bin. I don't really get where it comes from in the overlay part so I couldn't reverse engineer the
