tokio-async-await 0.1.7

Experimental async/await support for Tokio

Tokio async/await preview

This crate provides a preview of Tokio with async / await support. It is a shim layer on top of tokio.

This crate requires Rust nightly and does not provide API stability guarantees. You are living on the edge here.


To use this crate, you need to start with a Rust 2018 edition crate, with rustc 1.35.0-nightly or later.

Add this to your Cargo.toml:

# In the `[packages]` section
edition = "2018"

# In the `[dependencies]` section
tokio = {version = "0.1.15", features = ["async-await-preview"]}

Then, get started. In your application, add:

// The nightly features that are commonly needed with async / await
#![feature(await_macro, async_await, futures_api)]

// This pulls in the `tokio-async-await` crate. While Rust 2018 doesn't require
// `extern crate`, we need to pull in the macros.
extern crate tokio;

fn main() {
    // And we are async...
    tokio::run_async(async {

Because nightly is required, run the app with cargo +nightly run
