This allows tokio-signal to build with `-Z minimal-versions` - see https://github.com/rust-lang/cargo/issues/5657#issuecomment-401110172 for more details. Earlier versions depend on log 0.3.1, which itself depends on libc 0.1, which doesn't build on any post-1.0 version of rust.
tokio-signal
An implementation of Unix signal handling for Tokio
Usage
First, add this to your Cargo.toml:
[dependencies]
tokio-signal = "0.1"
Next you can use this in conjunction with the tokio and futures crates:
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)));
}
