Array Pool Scope

Array Pool Scope allows you to use ArrayPool in a scope-like manner.

🌟 Features

🚀 Fast and Safe - Use ArrayPool in a scope-like manner using readonly structs with no allocations!
✂ Fully trimmable and AOT compatible - No reflection or dynamic code is used, making it fully compatible with AOT platforms like NativeAOT and IL2CPP!
🌐 Wide range of .NET support - Supports .NET Standard 1.1 and up, including .NET Framework 4.6.1, .NET 5+ and even Unity!
✅ 100% test coverage - All code is tested to make sure it works as expected!
🗑 Almost zero allocations - The library is designed to be as allocation-free as possible!¹
📕 Fully documented - Every public member is documented with XML docs to make it easy to understand how to use the library!

¹ Sort(Comparison<T>) will allocate a small amount of memory in anything below .NET 5 due to the lack of efficient sorting methods.

💨 Quick Start

using Hertzole.Buffers;

int length = 10;
// Use a using statement to automatically return the array to the pool.
using (ArrayPoolScope<int> pool = new ArrayPoolScope<int>(length))
{
    // For loop
    for (int i = 0; i < pool.Length; i++)
    {
        pool[i] = i;
        Console.WriteLine(pool[i]);
    }

    // Foreach loop
    foreach (int item in pool)
    {
        Console.WriteLine(item);
    }
}

// Manully return the array to the pool.
ArrayPoolScope<int> pool = new ArrayPoolScope<int>(length);
pool.Dispose();

// Provide your own pool.
ArrayPool<int> customPool = ArrayPool<int>.Create();
using ArrayPoolScope<int> pool = new ArrayPoolScope<int>(length, customPool);

// Get directly from pool.
using ArrayPoolScope<int> pool = ArrayPool<int>.Shared.RentScope(length);

// As span and memory.
using ArrayPoolScope<int> pool = ArrayPool<int>.Shared.RentScope(length);
Span<int> span = pool.AsSpan();
Memory<int> memory = pool.AsMemory();

// Control how the array is cleared when disposed.
ArrayClearMode clearMode = ArrayClearMode.Auto; // Auto, Always, Never
using ArrayPoolScope<int> pool = new ArrayPoolScope<int>(length, clearMode);

// Get the array directly if needed. (you should avoid this, unless you really need the array)
using ArrayPoolScope<int> pool = ArrayPool<int>.Shared.RentScope(length);
int[] array = UnsafeArrayPool.GetArray(pool);
