Install
-------

[](#install)

```
composer require react-parallel/react-parallel

```

Usage
-----

[](#usage)

The factory in this package provides the following methods for quick and shared access to low level components.

```
$loop = EventLoopFactory::create();
$factory = new Factory($loop);
$factory->loop(); // Returns the event loop, mainly for convenience
$factory->eventLoopBridge(); // Returns the event loop bridge, used as a central place to translate channels and futures to observables and promises
$factory->streams(); // Returns the stream factory, which provides high level stream abstractions
$factory->call(function (int $time): int {
    return $time;
}, [time()]); // Executes the closure passed into this method in a thread and returns a promises for any results coming out of that closure
$factory->lowLevelPool(); // Returns a low level pool that will scale infinitely (as a long as you have resources enough to scale)
$factory->limitedPool(12); // Returns a limited pool with a maximum number of threads specified by you
```

Metrics
-------

[](#metrics)

This package supports metrics through [`wyrihaximus/metrics`](https://github.com/wyrihaximus/php-metrics):

```
use ReactParallel\Factory;
use ReactParallel\Metrics;
use WyriHaximus\Metrics\Configuration;
use WyriHaximus\Metrics\InMemory\Registry;

$registry = new Registry(Configuration::create());
$factory = (new Factory())->withMetrics(Metrics::create($registry));
```
