I'm trying to build a project. It uses pydantic, which uses maturin. How do I add maturin to the overrides? maturin is written in rust... here is my default.nix:

{ pkgs ? import <nixpkgs> {} }:
let
  pypkgs-build-requirements = {
    annotated-types = [ "hatchling" ];
    urllib3 = [ "hatchling" ];
    pydantic-core = [ pkgs.maturin ];
  };
  overrides = pkgs.poetry2nix.defaultPoetryOverrides.extend (self: super:
    builtins.mapAttrs (package: build-requirements:
      (builtins.getAttr package super).overridePythonAttrs (old: {
        buildInputs = (old.buildInputs or [ ]) ++ (builtins.map (pkg: if builtins.isString pkg then builtins.getAttr pkg super else pkg) build-requirements);
      })
    ) pypkgs-build-requirements
  );
in pkgs.poetry2nix.mkPoetryApplication {
  projectDir = ./.;
  overrides = overrides;
}

here is the pyproject.toml:

[tool.poetry]
name = "app"
version = "0.1.0"
description = ""
authors = ["danielg"]
readme = "README.md"
#packages = [{include = "src/scripts/*.py"}]

[tool.poetry.dependencies]
python = "^3.10"
dash = "^2.11.0"
plotly = "^5.15.0"
pandas = "^2.0.2"
dash-bootstrap-components = "^1.4.1"
python-dotenv = "^1.0.0"
pymysql = "^1.1.0"
sqlalchemy = "^2.0.17"
openpyxl = "^3.1.2"
pydantic = "^2.0"

[tool.poetry.scripts]
web-app = "poetry.console.application:main"

[build-system]
requires = ["poetry-core"]
build-backend = "poetry.core.masonry.api"

In reply to @FRidh:matrix.org
A while ago the flake interface for poetry2nix changed. Is there a description somewhere about how to use it now?

OK this was kind of what I was looking for

inherit (poetry2nix.lib.mkPoetry2Nix { inherit pkgs; }) mkPoetryPackages mkPoetryEnv overrides;
