Function pyo3_asyncio::async_std::run

pub fn run<F, T>(py: Python<'_>, fut: F) -> PyResult<T>where
    F: Future<Output = PyResult<T>> + Send + 'static,
    T: Send + Sync + 'static,

Run the event loop until the given Future completes

Arguments

• py - The current PyO3 GIL guard
• fut - The future to drive to completion

Examples

fn main() {
    // call this or use pyo3 0.14 "auto-initialize" feature
    pyo3::prepare_freethreaded_python();

    Python::with_gil(|py| {
        pyo3_asyncio::async_std::run(py, async move {
            async_std::task::sleep(Duration::from_secs(1)).await;
            Ok(())
        })
        .map_err(|e| {
            e.print_and_set_sys_last_vars(py);
        })
        .unwrap();
