Expand description
Spawn a task onto the default executor, yielding a
JoinHandle

representing the completion of the spawned task.

use futures::prelude::*;
use futures::future;
use futures::executor::{block_on, spawn_with_handle};
let future = future::ok::<u32, Never>(1);
let join_handle = block_on(spawn_with_handle(future))?;
let result = block_on(join_handle);
assert_eq!(result, Ok(1));
use futures::prelude::*;
use futures::future;
use futures::executor::{block_on, spawn_with_handle};
let future = future::err::<Never, &str>("boom");
let join_handle = block_on(spawn_with_handle(future))?;
let result = block_on(join_handle);
assert_eq!(result, Err("boom"));
