    F: FnOnce() -> PyResult<R>, 

👎 Deprecated since 0.14.0:

Use the pyo3_asyncio::async_std::run or pyo3_asyncio::tokio::run instead (see the migration guide for more details)

Wraps the provided function with the initialization and finalization for PyO3 Asyncio

This function MUST be called from the main thread.

Arguments

• py - The current PyO3 GIL guard
• f - The function to call in between intialization and finalization

Examples

use pyo3::prelude::*;

fn main() {
    // Call this function or use pyo3's "auto-initialize" feature
    pyo3::prepare_freethreaded_python();

    Python::with_gil(|py| {
        pyo3_asyncio::with_runtime(py, || {
            println!("PyO3 Asyncio Initialized!");
            Ok(())
        })
        .map_err(|e| {
            e.print_and_set_sys_last_vars(py);  
        })
        .unwrap();
    })
