Switon's synchronization primitives for bounded handoff, mutual exclusion, task joining, and LIFO reuse in coroutine and non-coroutine runtimes.

Highlights
----------

[](#highlights)

- **Coroutine-friendly primitives:** the same contracts work in coroutine and non-coroutine runtimes.
- **Bounded channels:** `Channel` provides fixed-capacity FIFO handoff.
- **Scoped mutexes:** `Mutex::guard()` returns a lock for deterministic release.
- **Task joining:** `WaitGroup` blocks until registered work finishes.
- **LIFO reuse:** `Stack` provides fixed-capacity last-in-first-out reuse.

Installation
------------

[](#installation)

```
composer require switon/sync
```

Quick Start
-----------

[](#quick-start)

```
use Switon\Sync\Channel;
use Switon\Sync\Mutex;
use Switon\Sync\WaitGroup;

$channel = new Channel(2);
$channel->push('task-1');
$task = $channel->pop();

$mutex = new Mutex();
$lock = $mutex->guard();
try {
    // critical section
} finally {
    $lock->release();
}

$wg = WaitGroup::of(2);
$wg->done();
$wg->done();
$wg->wait();
```
