pub fn future_into_py<F>(py: Python<'_>, fut: F) -> PyResult<&PyAny> where
    F: Future<Output = PyResult<PyObject>> + Send + 'static, 

Convert a Rust Future into a Python awaitable

Arguments

• py - The current PyO3 GIL guard
• fut - The Rust future to be converted

Examples

use std::time::Duration;

use pyo3::prelude::*;

/// Awaitable sleep function
#[pyfunction]
fn sleep_for<'p>(py: Python<'p>, secs: &'p PyAny) -> PyResult<&'p PyAny> {
    let secs = secs.extract()?;
    pyo3_asyncio::async_std::future_into_py(py, async move {
        async_std::task::sleep(Duration::from_secs(secs)).await;
        Python::with_gil(|py| Ok(py.None()))
    })
}
