Function spawn_with_return 

pub fn spawn_with_return<F: SpawnableWithReturn<Out>, Out: Spawnable>(
    f: F,
) -> Receiver<<Out as Future>::Output> 

Spawns a async job to run f (the future passed) and returns a futures::channel::oneshot::Receiver which can be used to get the return value from f.

See the examples folder for more complete examples.

Example

 let task = async || { "hi".to_owned() };
 let rx = spawn_with_return(task);

 let result = rx.await?; //Only an example, in a real use case use try_recv instead
 assert_eq!(result, "hi");
