AsyncUsableLock

AsyncUsableLock is an async-friendly lock that supports the using-disposal pattern.

It is useful when you need to protect a critical section in an async method (where lock (...) { ... } cannot be used with await).

Basic usage (await + using)

using Garyon.Mechanisms;

private readonly AsyncUsableLock _gate = new();

public async Task UpdateAsync()
{
    using var releaser = await _gate.LockAsync();

    // This section is protected; it is released when `releaser` is disposed.
    await Task.Delay(10);
}

Non-blocking attempt (TryLock)

If you want to skip work when the lock is already held:

using Garyon.Mechanisms;

var gate = new AsyncUsableLock();

using var releaser = gate.TryLock(out var success);
if (!success)
    return;

// Protected work...

Cancellation

If you need a cancellable wait for the lock:

using var releaser = await _gate.LockAsync(cancellationToken);
