Compatibility layers between tokio 0.2 and legacy versions.
Website | Guides | API Docs | Chat
This crate provides compatibility runtimes that allow running both futures 0.1
futures that use tokio 0.1 runtime services and std::future futures that
use tokio 0.2 runtime services.
Spawning both tokio 0.1 and tokio 0.2 futures:
use futures_01::future::lazy;
tokio_compat::run(lazy(|| {
// spawn a `futures` 0.1 future using the `spawn` function from the
// `tokio` 0.1 crate:
tokio_01::spawn(lazy(|| {
println!("hello from tokio 0.1!");
Ok(())
}));
// spawn an `async` block future on the same runtime using `tokio`
// 0.2's `spawn`:
tokio_02::spawn(async {
println!("hello from tokio 0.2!");
});
Ok(())
}))Futures on the compat runtime can use timer APIs from both 0.1 and 0.2
versions of tokio:
use std::time::{Duration, Instant};
use futures_01::future::lazy;
use tokio_compat::prelude::*;
tokio_compat::run_std(async {
// Wait for a `tokio` 0.1 `Delay`...
let when = Instant::now() + Duration::from_millis(10);
tokio_01::timer::Delay::new(when)
// convert the delay future into a `std::future` that we can `await`.
.compat()
.await
.expect("tokio 0.1 timer should work!");
println!("10 ms have elapsed");
// Wait for a `tokio` 0.2 `Delay`...
let when = Instant::now() + Duration::from_millis(20);
tokio_02::timer::delay(when).await;
println!("20 ms have elapsed");
