stack overflow with a certain Rust project

[yusdacra]

It seems the Rust builder will stack overflow if used on the helix repo. I've tested the translator separately, which works fine. This also happens on #83 with the crane builder, so it doesn't seem to be specific to the buildRustPackage builder.

repro:

{
  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
    dream2nix = {
      url = "github:nix-community/dream2nix";
      inputs.nixpkgs.follows = "nixpkgs";
    };
    helix = {
      url = "github:helix-editor/helix";
      flake = false;
    };
  };

  outputs = inputs@{ nixpkgs, dream2nix, helix, ... }:
    let
      system = "x86_64-linux";
      dream2nix = inputs.dream2nix.lib.init {
        pkgs = nixpkgs.legacyPackages.${system};
      };
    in dream2nix.riseAndShine { source = helix; };
}

Fixed this on #83. The issue was that the code that got all transitive dependencies were handling cyclic dependencies incorrectly, which caused it to recurse infinitely. I'll keep this open until #83 gets merged.
