Install
-------

[](#install)

To install via Composer, use the command below :

```
composer require azjezz/mutex
```

About
-----

[](#about)

This package provides two things:

- An interface for [`mutex` locking](https://en.wikipedia.org/wiki/Mutual_exclusion)
- A in-memory implementation of that interface

Example
-------

[](#example)

```
use namespace AzJezz\Mutex;
use namespace HH\Asio;

require 'vendor/autoload.hack';

async function main(): Awaitable {
  Facebook\AutoloadMap\initialize();

  $mutex = new Mutex\Memory();

  $jobs = vec[
    foo($mutex), // first to acquire the lock
    foo($mutex), // won't be able to acquire the lock
    foo($mutex), // same
  ];

  foreach($jobs as $job) {
    await $job;
  }
}

async function foo(
  Mutex\MutexInterface $mutex
): Awaitable {
  $lock = await $mutex->acquire('foo');
  if ($lock is nonnull) {
    echo "doing things \n";
    await Asio\usleep(10000000);
    echo "finished my job, releasing the lock \n";
    await $mutex->release($lock);
    return;
  }

  echo "someone else have requested the 'foo' lock\n";
}
```
