cargo-features not applied

Using the following overlay:

self: super: rec {
  crate2nix-tools =
      import ((builtins.fetchTarball sources.crate2nix.url) + "/tools.nix")
      {};
  nil-src =
      import
      (crate2nix-tools.generatedCargoNix {
        name = "nil";
        src = builtins.fetchTarball sources.nil.url;
      })
      {
      inherit super; rootFeatures = ["edition2021"];
      };
  nil = nil-src.rootCrate.build;
}

I still end up getting:

@nix { "action": "setPhase", "phase": "unpackPhase" } unpacking sources unpacking source archive /nix/store/0krjcwvk4fdcxjl1is0iqx0y1iz9f5vj-source source root is source @nix { "action": "setPhase", "phase": "buildPhase" } building ++ crate2nix generate -f ./Cargo.toml -o Cargo-generated.nix -h /nix/store/qwv4hzwvaspk593acq8fxwacllp5dp09-nil-crate2nix/crate-hashes.json Error: while retrieving metadata about ./Cargo.toml: cargo metadata exited with an error: error: failed to parse manifest at /tmp/nix-build-nil-crate2nix.drv-0/source/Cargo.toml

Caused by: feature edition2021 is required

The package requires the Cargo feature called edition2021, but that feature is not stabilized in this version of Cargo (1.55.0). Consider adding cargo-features = ["edition2021"] to the top of Cargo.toml (above the [package] table) to tell Cargo you are opting in to use this unstable feature. See https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#edition-2021 for more information about the status of this feature. crate2nix failed. == cargo/config (BEGIN) [source.crates-io] replace-with = "vendored-sources"
