Cycle in the struct layout that doesn't exist

Question

This is a simplified version of some of my code:

public struct info
{
    public float a, b;
    public info? c;

    public info(float a, float b, info? c =

Disclaimer: This may not achieve the goal of "struct like value type behaviour."

One solution is to use an array of one item to essentially get a reference the recursively referenced structure. Adapting my approach to your code looks something like this.

public struct info
{
    public float a, b;
    public info? c
    {
        get
        {
            return cArray[nextIndex];
        }
        set
        {
            steps[nextIndex] = value;
        }
    }
    private info?[] cArray;

    public info(float a, float b, info? c = null)
    {
        this.a = a;
        this.b = b;
        this.cArray = new info?[] { c }
        this.c = c;
    }
}
