pub struct Spawner { /* fields omitted */ }

A spawner for a multi-threaded executor.

Implementations

impl Spawner

pub fn current() -> Spawner

Gets a spawner for the current multi-threaded executor.

If called from an Executor, returns its Spawner.

Otherwise, this method panics.

Examples

use async_executor::{Executor, Spawner};

let ex = Executor::new();

ex.run(async {
    let spawner = Spawner::current();
    let task = spawner.spawn(async { 1 + 2 });
    assert_eq!(task.await, 3);
});

pub fn spawn<T: Send + 'static>(
    &self,
    future: impl Future<Output = T> + Send + 'static
) -> Task<T>ⓘ

Important traits for Task<T>

impl<T> Future for Task<T> type Output = T;

Examples

use async_executor::Executor;

let ex = Executor::new();
let spawner = ex.spawner();

let task = spawner.spawn(async {
    println!("Hello world");
});
