Function glib::unix_signal_future

Important traits for Box<R>

impl<R> Read for Box<R> where
    R: Read + ?Sized, impl<W> Write for Box<W> where
    W: Write + ?Sized, impl<I> Iterator for Box<I> where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;

pub fn unix_signal_future(
    signum: i32
) -> Box<Future<Item = (), Error = Never> + Send>

Create a Future that will resolve once the given UNIX signal is raised

The Future must be spawned on an Executor backed by a glib::MainContext.
