# executor

<a href="https://docs.rs/executor"><img src="https://img.shields.io/badge/docs-latest-blue.svg?style=flat-square" alt="docs.rs docs" /></a>

```toml
[dependencies]
executor = "0.8"
```
## Features
- [x] `#![no_std]` + `alloc`
- [x] simple enough to learn from! (~ 100 lines)
- [x] works with WebAssembly

## WebAssembly

```rust
use web::*;

#[no_mangle]
fn main() {
    executor::run(async {
        loop {
            set_inner_html(DOM_BODY, "⏰ tic");
            sleep(1000).await;
            set_inner_html(DOM_BODY, "⏰ tock");
            sleep(1000).await;
        }
    });
}
```

See this working [here](https://richardanaya.github.io/executor/examples/timer/).

## CLI

Even `async-std` can be used if you add something to stop it from exiting too early.

```rust
use async_std::task::sleep;
use std::time::Duration;

fn main() {
    let complete = std::sync::Arc::new(core::sync::atomic::AtomicBool::new(false));
    let ender = complete.clone();
    executor::run(async move {
        println!("hello");
        sleep(Duration::from_secs(1)).await;
        println!("world!");
        ender.store(true, core::sync::atomic::Ordering::Release);
    });
    while !complete.load(core::sync::atomic::Ordering::Acquire) {}
}
```
