Ok. Found makeRustPlatform

I think this is the cause of the error I'm currently receiving

I've just tried to upgrade nixpkgs-unstable and it looks like the vector package is failing to build with:

       error: attribute 'targetPlatforms' missing
       at /nix/store/riqkpszjqk02bi1wppfg8ip5xvh102qd-source/pkgs/build-support/rust/build-rust-package/default.nix:162:7:

             |       ^
          163|   };

did something change there? Am I even seeing the right error message?
