zig does not allow arrays in packed structs/unions specifically for endianness reasons (there may be other reasons as well but endianness is what i know of)

- tremon 3mo agoAh, that is useful to know. Is that documented somewhere? From what I can quickly find in the obvious place [0], the only requirement is that "all fields in a packed union must have the same @bitSizeOf" and [2]u8 does satisfy that requirement.

- peesem 3mo agono, but the documentation for packed structs gives the list of allowed field types. it's also not documented that packed union fields must be valid packed struct fields but people may be able to assume that edit: also, this is a relevant issue: https://github.com/ziglang/zig/issues/12547 https://github.com/ziglang/zig/issues/12547
