IFD does not work with git deps about crate2nix HOT 2 OPEN

I think rust version that gets passed to "${crate2nix}/tools.nix" is different from rust version you get when you nix run, try checking that.

from crate2nix.

That seems to not be the source of the issue.

nix run

When I nix run it uses cargo 1.76.0 as pinned in your nixpkgs, since nix derivation show github:nix-community/crate2nix shows /nix/store/8s7fd4c5r06d4x94vqbmgwsv05v2jmlb-cargo-1.76.0.drv, UNLESS there is also another cargo version in path, in which case it uses that one.
Either way (1.76.0 or my 1.77.0) I don't get any error when running crate2nix generate, and build then runs - although the generated files look different in that they don't use the same ID format.

IFD

I was doing (pkgs.callPackage "${crate2nix}/tools.nix" { }).generatedCargoNix, which had me override the pkgs, but I happened to also have 1.76 there (/nix/store/7ld12b9gmdziwrvjyb1lhf5y49b7l0nw-cargo-1.76.0.drv).
I also tried using crate2nix.tools.${system}.generatedCargoNix, which prevents me from overriding and instead uses the version that you're exporting, but that does result in the same error, despite it picking the exact same derivation as non-ifd: /nix/store/8s7fd4c5r06d4x94vqbmgwsv05v2jmlb-cargo-1.76.0.drv.

So it would look like that's not the source of the issue.

I also made sure to be generating the Cargo.lock on 1.76 if that matters.

Side note

• When building afterwards - if I get to that point - and in the associated dev shell, I'm then using latest stable from oxalica:

          {
            buildRustCrateForPkgs = pkgs: pkgs.buildRustCrate.override (
              let rustToolchain = pkgs.rust-bin.stable.latest; in {
                # Use the latest stable rust version from oxalica overlay instead of the one in nixpkgs to build workspace packages
                # https://github.com/NixOS/nixpkgs/blob/master/doc/languages-frameworks/rust.section.md
                # https://github.com/NixOS/nixpkgs/blob/master/pkgs/build-support/rust/build-rust-crate/default.nix#L12-L13
                rustc = rustToolchain.default;
                cargo = rustToolchain.cargo;
                # We need to override some dependencies/env variables... for some crates - that is specified in crate_overrides.nix
                defaultCrateOverrides = pkgs.callPackage ./crate_overrides.nix { inherit flake-inputs packages cargoNix; };
              }
            );
          };

That's currently pinned at 1.77.0 in the flake.
If it matters that this is the same version that we generate the Cargo.nix for (that Cargo.lock is generated with...), then I wonder how I could override tools.nix to have it use that version from my pkgs.rust-bin - there doesn't seem to be a corresponding argument.

from crate2nix.
