[−][src]Function tokio::task::spawn_local

Important traits for JoinHandle<T>

impl<T> Future for JoinHandle<T> type Output = Result<T, JoinError>;

pub fn spawn_local<F>(future: F) -> JoinHandle<F::Output> where
    F: Future + 'static,
    F::Output: 'static,

This is supported on feature="rt-core" and feature="rt-util" only.

Spawns a !Send future on the local task set.

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;

let unsend_data = Rc::new("my unsend data...");

let mut rt = Runtime::new().unwrap();
let local = task::LocalSet::new();

// Run the local task set.
local.block_on(&mut rt, async move {
    let unsend_data = unsend_data.clone();
    task::spawn_local(async move {
        println!("{}", unsend_data);
        // ...
    }).await.unwrap();
});
