This is important when you want e.g. wrap the output binary with for example postInstall.

nix-rust.lib.build.buildRustPackage {
   ...
   postInstall = ''
     wrapProgram $out/bin/my-app \
      --set MY_ENV "yoink"
   '';
}

This is not possible in the current implementation,
because $out/bin/my-app does not exist in the dependency derivation.

With the changes it will be possible to write the above as:

nix-rust-lib.build.buildRustPackage {
  ...
  binaryArgs.postInstall = ''
    wrapProgram $out/bin/my-app \
      --set MY_ENV "yoink"
    '';
}
``

The new options are:
- `binaryArgs` -> for binary derivation
- `dependencyArgs` -> for dependency derivation

This is important when you want e.g. wrap the output binary with for example `postInstall`. ```nix nix-rust.lib.build.buildRustPackage { ... postInstall = '' wrapProgram $out/bin/my-app \ --set MY_ENV "yoink" ''; } ``` This is not possible in the current implementation, because `$out/bin/my-app` does not exist in the dependency derivation. With the changes it will be possible to write the above as: ```nix nix-rust-lib.build.buildRustPackage { ... binaryArgs.postInstall = '' wrapProgram $out/bin/my-app \ --set MY_ENV "yoink" ''; } `` The new options are: - `binaryArgs` -> for binary derivation - `dependencyArgs` -> for dependency derivation
