Call a pyfunction implemented in PyO3 from the same rust program

[qt2]

Is it possible to call a pyfunction implemented in PyO3 from the same rust program?
For example:

#[pyfunction]
fn one() -> f32 {
    1.
}

fn main() {
    let gil = Python::acquire_gil();
    let py = gil.python();
    // I'd like to call the function like this:
    py.run("print(one())");
}

In a binary crate, it seems that the functions are not loaded automatically by the #[pyfunction] macro, but I couldn't find a way to load them manually either.

I use the latest stable versions of Rust and PyO3.

Take a look at pyo3::py_run

#[pyfunction]
fn one() -> f32 {
    1.
}

fn main() {
    let gil = Python::acquire_gil();
    let py = gil.python();
    let one = wrap_pyfunction!(one)(py).unwrap();
    pyo3::py_run!(py, one, "print(one())");
}

@messense Thank you for your advice. It completely solved my problem.
