Function pyo3_asyncio::generic::future_into_py_with_loop

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

Convert a Rust Future into a Python awaitable with a generic runtime

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::generic::future_into_py_with_loop::<MyCustomRuntime, _>(
        pyo3_asyncio::generic::get_current_loop::<MyCustomRuntime>(py)?,
        async move {
            MyCustomRuntime::sleep(Duration::from_secs(secs)).await;
            Python::with_gil(|py| Ok(py.None()))
        }
    )
