This library is an implementation of zero-cost futures in Rust.

Build Status Crates.io




First, add this to your Cargo.toml:

futures = "0.2.1"

Next, add this to your crate:

extern crate futures;

use futures::Future;

For more information about how you can use futures with async I/O you can take a look at https://tokio.rs which is an introduction to both the Tokio stack and also futures.

Feature std

futures-rs works without the standard library, such as in bare metal environments. However, it has a significantly reduced API surface. To use futures-rs in a #[no_std] environment, use:

futures = { version = "0.2.1", default-features = false }
