# tokio-signal

An implementation of Unix signal handling for Tokio

[![Build Status](https://travis-ci.org/alexcrichton/tokio-signal.svg?branch=master)](https://travis-ci.org/alexcrichton/tokio-signal)

[Documentation](https://docs.rs/tokio-signal)

## Usage

First, add this to your `Cargo.toml`:

```toml
[dependencies]
tokio-signal = "0.2"
```

Next you can use this in conjunction with the `tokio` and `futures` crates:

```rust,no_run
extern crate futures;
extern crate tokio;
extern crate tokio_signal;

use futures::{Future, Stream};

fn main() {

    // Create an infinite stream of "Ctrl+C" notifications. Each item received
    // on this stream may represent multiple ctrl-c signals.
    let ctrl_c = tokio_signal::ctrl_c().flatten_stream();

    // Process each ctrl-c as it comes in
    let prog = ctrl_c.for_each(|()| {
        println!("ctrl-c received!");
        Ok(())
    });

    tokio::run(prog.map_err(|err| panic!("{}", err)));
}
```
