Rust crate for waiting on a `Child` process with a timeout specified.

```sh

$ cargo add wait-timeout

```

Example:

```rust

use std::io;

use std::process::Command;

use std::time::{Duration, Instant};

use wait_timeout::ChildExt;

fn main() -> io::Result<()> {

    let mut child = Command::new("sleep").arg("100").spawn()?;

    let start = Instant::now();

    assert!(child.wait_timeout(Duration::from_millis(100))?.is_none());

    assert!(start.elapsed() > Duration::from_millis(100));

    child.kill()?;

    let start = Instant::now();

    assert!(child.wait_timeout(Duration::from_millis(100))?.is_some());

    assert!(start.elapsed() < Duration::from_millis(100));

    Ok(())

}

```
