async-std v1.4.0 Release Notes

Release Date: 2019-12-20 // over 4 years ago

  • 📚 API Documentation

    ⏱ This patch adds Future::timeout, providing a method counterpart to the 🛠 future::timeout free function. And includes several bug fixes around missing APIs. Notably we're not shipping our new executor yet, first announced on our blog.

    Examples

    use async_std::prelude::*;
use async_std::future;
use std::time::Duration;

let fut = future::pending::<()>(); // This future will never resolve.
let res = fut.timeout(Duration::from_millis(100)).await;
assert!(res.is_err()); // The future timed out, returning an err.
