Examples

Example #1 Checking before and after start

<?php

use function Async\spawn;
use function Async\suspend;
use function Async\await;

$coroutine = spawn(function() {
    return "test";
});

var_dump($coroutine->isStarted()); // bool(false) -- still in queue

suspend(); // let the scheduler start the coroutine

var_dump($coroutine->isStarted()); // bool(true)

await($coroutine);

var_dump($coroutine->isStarted()); // bool(true) -- still true after completion
