enum Point {
    Nothing,

    StructPoint {

Hi, welcome to the forum. Is there any question you wanted to ask? Maybe you hit the post button prematurely? (Sorry for the delay, our spam filter can hold copy-pasted first posts, and it looks like you didn’t get any further than pasting your code example in the editor.)

Also, I fixed the formatting for you :wink:
