async-std
Async version of the Rust standard library
This crate provides an async version of [`std`]. It provides all the interfaces
you are used to, but in an async version and ready for Rust's `async`/`await`
syntax.
[`std`]: https://doc.rust-lang.org/std/index.html
## Features
- __Modern:__ Built from the ground up for `std::future` and `async/await` with
blazing fast compilation times.
- __Fast:__ Our robust allocator and threadpool designs provide ultra-high
throughput with predictably low latency.
- __Intuitive:__ Complete parity with the stdlib means you only need to learn
APIs once.
- __Clear:__ [Detailed documentation][docs] and [accessible guides][book] mean
using async Rust was never easier.

## Examples
```rust
use async_std::task;
fn main() {
task::block_on(async {
println!("Hello, world!");
})
}
```
More examples, including networking and file access, can be found in our
[`examples`] directory.

## Philosophy
We believe Async Rust should be as easy to pick up as Sync Rust. We also believe
that the best API is the one you already know. And finally, we believe that
providing an asynchronous counterpart to the standard library is the best way
stdlib provides a reliable basis for both performance and productivity.
Async-std is the embodiment of that vision. It combines single-allocation task
creation, with an adaptive lock-free executor, threadpool and network driver to
create a smooth system that processes work at a high pace with low latency,
using Rust's familiar stdlib API.
## Installation
With [cargo add][cargo-add] installed run:
```sh
$ cargo add async-std
```
We also provide a set of "unstable" features with async-std. See the [features
documentation] on how to enable them.
