Expand description
Spawns a !Send

The spawned future will be run on the same thread that called spawn_local.
This may only be called from the context of a local task set.
Panics
- This function panics if called outside of a local task set.
Examples
use std::rc::Rc;
use tokio::task;
#[tokio::main]
async fn main() {
let unsend_data = Rc::new("my unsend data...");
let local = task::LocalSet::new();
// Run the local task set.
local.run_until(async move {
let unsend_data = unsend_data.clone();
task::spawn_local(async move {
println!("{}", unsend_data);
// ...
}).await.unwrap();
}).await;
