Function pyo3_asyncio::tokio::cancellable_future_into_py_with_loop

pub fn cancellable_future_into_py_with_loop<F>(
    event_loop: &PyAny, 
    fut: F
) -> PyResult<&PyAny> where
    F: Future<Output = PyResult<PyObject>> + Send + 'static, 

👎 Deprecated since 0.15.0:

Use pyo3_asyncio::tokio::future_into_py_with_locals instead

Convert a Rust Future into a Python awaitable

This function was deprecated in favor of future_into_py_with_locals in v0.15 because it became the default behaviour. In v0.15, any calls to this function should be replaced with future_into_py_with_locals.

This function will be removed in v0.16

Arguments

• event_loop - The Python event loop that the awaitable should be attached to
• 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::tokio::cancellable_future_into_py_with_loop(
        pyo3_asyncio::tokio::get_current_loop(py)?,
        async move {
            tokio::time::sleep(Duration::from_secs(secs)).await;
            Ok(Python::with_gil(|py| py.None()))
        }
    )
}
