Fields remain in source order.\n\nThis is useful where the structure is unlikely to be correctly aligned (the insertion rules for padding assume it is), or if the space-savings are more important or useful than the access speed of the fields.\n\nAccessing a field in a packed struct may require copying the field out of the struct into a temporary location, or using a machine instruction that doesn’t assume the pointer address is correctly aligned, in order to be performant or avoid crashing on some systems.

 	"align" = "```odin\n#align\n```\n\nThis tag can be applied to a `struct` or `union`. When `#align` is passed an integer `N` (as in `#align N`), it specifies that the `struct` will be aligned to `N` bytes. The `struct`’s fields will remain in source-order.",
