The pyfrozen class example dosent work

[psvri]

Hello Folks,

While going through the user guide for the pyclass frozen I see that the code given in the example dosent compile and I get the error no method namedgetfound for structpyo3::Py in the current scope . Also a side note I dont find that function in the docs as well . Can you let me know the fixes that needs to be done in the example for it to work ? .Below is the full code given in the docs

#![allow(unused)]
fn main() {
use std::sync::atomic::{AtomicUsize, Ordering};
use pyo3::prelude::*;

#[pyclass(frozen)]
struct FrozenCounter {
    value: AtomicUsize,
}

let py_counter: Py<FrozenCounter>  = Python::with_gil(|py| {
    let counter = FrozenCounter { value: AtomicUsize::new(0) };

    Py::new(py, counter).unwrap()
});

py_counter.get().value.fetch_add(1, Ordering::Relaxed);
}

I think you are looking at the guide for the main branch as indicated by your link but build against a released version of PyO3, probably 0.18.3? Py::get was merged only recently and is not yet part of a released version.

You can either read the guide for the released version at e.g. https://pyo3.rs/v0.18.3/class.html or build against the main branch using a Git dependency like

pyo3 = { git = "https://github.com/PyO3/pyo3.git" }

Oops, I failed to realize this.

Thanks for the help.
