tokio-scoped

tokio-scoped provides a scope function and ScopedRuntime struct inspired by crossbeam but for the tokio Runtime. A scope allows one to spawn futures which do not have a 'static lifetime by ensuring each future spawned in the scope completes before the scope exits.

Example

# extern crate tokio_scoped;
# extern crate futures;
# use futures::lazy;

let mut v = String::from("Hello");
tokio_scoped::scope(|scope| {
    // Use the scope to spawn the future.
    scope.spawn(lazy(|| {
        v.push('!');
        Ok(())
    }));
});
// The scope won't exit until all spawned futures are complete.
assert_eq!(v.as_str(), "Hello!");
