Wrote this blog post to summarize what I think are the right ways to understand alignment and size for various data types in Zig, just through experimentation.

Let me know any and all feedback!

    struct Dang : bits 64    // 64 bits wide, int total
    {
        foo : bits 5 @ 0;    // 5 bits wide at bit offset 0
        bar : bits 5 @ 0;
        baz : bits 16 @ 4;   // 16 bits wide at bit offset 4
        tom : bits 11 @ 32;
    };

I have worked with a number of fresh grads over the last ten years. I can think of one who may have had a good handle on this. At best the rest range from “vague memory recall about this” to a blank stare.

On the flip hand, it’s something someone can pick up pretty quickly if motivated.
