Zero-cost asynchronous programming in Rust
Usage
Add this to your Cargo.toml:
[dependencies]
futures-preview = "=0.3.0-alpha.17"Now, you can use futures-rs:
use futures::future::Future; // Note: It's not `futures_preview`The current futures-rs requires Rust 1.36 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:
[dependencies]
futures-preview = { version = "=0.3.0-alpha.17", default-features = false }Feature async-await
The async-await feature provides several convenient features using unstable
async/await. Note that this is an unstable feature, and upstream changes can
make it cannot compile. To use futures-rs with async/await, use:
[dependencies]
futures-preview = { version = "=0.3.0-alpha.17", features = ["async-await", "nightly"] }The current async-await feature requires Rust nightly 2019-05-09 or later.
