Add this to your Cargo.toml:

futures-preview = "0.3.0-alpha.9"

Now, you can use futures-rs:

use futures::future::Future; // Note: It's not `futures_preview`

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-preview = { version = "0.3.0-alpha.9", default-features = false }
