On: What Makes the Zig Programming Language Unique?

[evil-olive]

regular structs in Zig have an implementation-defined layout in memory - the compiler is allowed to re-order fields, add padding, etc.

if you want control over the memory layout you need either a packed struct or an extern struct [0].

With respect, I’m not sure that answered the question. Surely in a sudoku game the default layout of structs would be absolutely fine, no?

ahh, I might have misunderstood the question - I wasn't sure if they were asking about Zig in general or my solver in particular.

yes, normal structs would have worked fine - like I said, I was learning Zig in the process, so I was going out of my way to experiment with its unique features.

Yes, I meant in your sudoku solver, sorry, I should've been more clear.
