Function pyo3_asyncio::generic::local_cancellable_future_into_py_with_loop [−][src]
pub fn local_cancellable_future_into_py_with_loop<R, F>(
event_loop: &PyAny,
fut: F
) -> PyResult<&PyAny> where
R: Runtime + SpawnLocalExt + LocalContextExt,
F: Future<Output = PyResult<PyObject>> + 'static, 👎 Deprecated since 0.15.0:
Use pyo3_asyncio::generic::local_future_into_py_with_locals instead
Expand description
Convert a !Send Rust Future into a Python awaitable with a generic runtime
This function was deprecated in favor of local_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 local_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 tofut- The Rust future to be converted
Examples
use std::{rc::Rc, time::Duration};
use pyo3::prelude::*;
/// Awaitable sleep function
#[pyfunction]
fn sleep_for<'p>(py: Python<'p>, secs: u64) -> PyResult<&'p PyAny> {
// Rc is !Send so it cannot be passed into pyo3_asyncio::generic::future_into_py
let secs = Rc::new(secs);
