executor

[dependencies]
executor = "0.6"

Features

• #![no_std] + alloc
• global executor for easy spawning
• simple enough to learn from! (~ 100 lines)
• simple macros for async entry functions

Example

A web assembly example

#[no_mangle]
#[executor::entry]
pub fn main() {
    console_log("Hello");
    set_timeout(1000).await;
    console_log("World!");
}

fn set_timeout(milliseconds:u32) -> TimeoutFuture {
   // create a timeout future and store globally
}

#[no_mangle]
pub fn timeout_complete() -> () {
    // find your timeout future and wake it's waker
}

async-std

Want to use async-std?

use async_std::task::sleep;
use std::time::Duration;

#[executor::main]
async fn main() {
    println!("hello");
    sleep(Duration::from_secs(1)).await;
    println!("world!");
}

Want to replace the global executor?

Write your own with this trait

pub trait GlobalExecutor {
    fn spawn(&mut self, future: Box<dyn Future<Output = ()> + 'static + Send + Unpin>);
}

executor::set_global_executor(MY_EXECUTOR);
