Crate futures_lite

Futures, streams, and async I/O combinators.

This crate is a subset of futures that compiles an order of magnitude faster, fixes minor warts in its API, fills in some obvious gaps, and removes almost all unsafe code from it.

In short, this crate aims to be more enjoyable than futures but still fully compatible with it.

The API for this crate is intentionally constrained. Please consult the features list for APIs that are occluded from this crate.

Examples

use futures_lite::future;

fn main() {
    future::block_on(async {
        println!("Hello world!");
    })
}
