This repository contains code that demonstrates the problem of accessing class fields from custom built-in module. When foo.name accessed (by getter or setter) the Expected payload "Foo" but "Foo" found error displays.

# sample/main.py

from framework import foo

f = foo.Foo()
f.name = "Bar" # <-- PROBLEM IS HERE: Expected payload "Foo" but "Foo" found

// rust implementation

#[pyattr]
#[pyclass(name = "Foo")]
#[derive(Debug, PyPayload)]
struct Foo {
    name: PyMutex<String>,
}

#[pyclass]
impl Foo {
    #[pygetset]
    fn name(&self) -> PyStr {
        PyStr::from(self.name.lock().as_str())
    }

    #[pygetset(setter)]
    pub fn set_name(&self, value: PySetterValue<PyStrRef>, _: &VirtualMachine) {
        let mut n = self.name.lock();
        *n = value.unwrap().as_str().to_string();
    }

}

See "Foo" source details.

What am I doing wrong ?

• rust
• rustpython 0.3.1
• rustpython-vm 0.3.1

Use command bellow to run the demo

cargo run --bin app

I need to create a scripting engine that integrates the Python interpreter and provides a framework that can be used in scripts. I want to implement the framework entirely in Rust.
