`futures-rs` is a library providing the foundations for asynchronous programming in Rust.

It includes key trait definitions like `Stream`, as well as utilities like `join!`,

`select!`, and various futures combinator methods which enable expressive asynchronous

control flow.

## Usage

Add this to your `Cargo.toml`:

```toml

[dependencies]

futures = "0.3"

```

The current `futures` requires Rust 1.56 or later.

### 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:

```toml

[dependencies]

futures = { version = "0.3", default-features = false }

```
