Mapping [64]u8 buffer to a struct

So does this really mean you cannot have packed structs that are odd size?

Looks exactly like this.

But apparently it is possible with so called extern structs, thanks to @IntegratedQuantum.
For example

const S = extern struct {
    a: u8 align(1),
    b: u8,
    c: u8,
};

has size 3 and alignment 1.
