@Sfonxu, the CI build now fails with:

Error:   --> src/main.rs:43:60
   |
43 |     let stepper_arg = vec![("options", options),("n_dims", 2)].into_py_dict_bound(py);
   |                                                            ^ expected `Bound<'_, PyAny>`, found integer
   |
   = note: expected struct `pyo3::Bound<'_, PyAny>`
                found type `{integer}`

As to comment on changes made to readme_rust.yml file:

• changed python toolchain version to v5
• changed rust toolchain to dtolnay/rust-toolchain@stable
  This seems to have worked and successfully compiled the rust example
