IEnumerableUnpacker 1.0.1

IEnumerableUnpacker 📦

IEnumerableUnpacker is a C# library that provides a quick and efficient way to unpack IEnumerable<T> to 1D and 2D arrays of T's members. It leverages parallel processing and optimized memory copying techniques to achieve high-performance array unpacking. 🚀

Key Features

• Unpack IEnumerable<T> to 1D and 2D arrays of T's members
• Utilize parallel processing for individual members ⚡
• Identify blittable types and use unaligned memory copy for optimized performance
• Support for generic types
• Flexible attribute-based configuration for specifying output parameter names

Installation

You can install IEnumerableUnpacker via NuGet Package Manager:

Install-Package IEnumerableUnpacker

Usage

Here's an example of how to use IEnumerableUnpacker:

[Unpackable]
public class UnpackMe<Titem, Titem2, UselessGeneric>
{
    [Unpack("MyItegersOut")]
    public int[] myIntegers;

    [Unpack("MyIntegerOut")]
    public int myInteger;

    [Unpack("MyFloatsOut")]
    public float[] myFloats;

    [Unpack("MyGenericOut")]
    public Titem[] myGeneric;

    [Unpack("MyGeneric2Out")]
    public Titem2 myGeneric2;
}

public static unsafe void UnpackUnpackMe<Titem, Titem2, UselessGeneric>(this IEnumerable<UnpackMe<Titem, Titem2, UselessGeneric>> source, out int[,] MyItegersOut, out int[] MyIntegerOut, out float[,] MyFloatsOut, out Titem[,] MyGenericOut, out Titem2[] MyGeneric2Out)
{
    // Unpacking logic...
}

In this example:

• The Unpackable attribute is used to mark the class for unpacking.
• The Unpack attribute is used to specify the output parameter names for the unpacked arrays.
• Generic types are supported and can be used as needed.
• Parameters not labeled with the Unpack attribute will not be unpacked.

Note

I've decided to use 2D arrays because that's what I use with TorchSharp. Unpacking to flat types might be faster, so feel free to reach out to me if it's required! 📫
