A library inspired in Unity.Collections that provides a set of containers that make use of unmanaged memory for hold their elements.

The main purpose is to provide containers that produces zero allocations and call Dispose after use.

Each container inherit from INativeContainer<T> and IDisposable.

public interface INativeContainer<T>
{
	public int Length { get; }
	public bool IsEmpty { get; }
	public int IsValid { get; }

	public void CopyTo(in Span<T> span, int index, int count);
}

NativeCollections offers containers that make use of unmanaged memory who is provide by an Allocator.

The containers are constrained to only store ValueTypesthat don't contains reference type on its fields.

At the time all the memory used for a container must be free manually or by declaring the container with using.

As all the containers use unmanaged memory they produce zero allocations, thus the Garbage Collection pressure is reduce, but keep in mind that that this allocations could be slower or faster than those that relied in GC depending the allocator used.

Here some benchmark of List<T> vs NativeList<T>, some optimization could be done in special with small allocations, by default all containers use DefaultHeapAllocator which make use of the HeapAllocator of kernel32.dll.
