I had an (implementation) question for you: Does the
implementation actually require knowing what the size of the
padding is?
eg:
struct A
{
int a;
mixin(bitfields!(
uint, "x", 2,
int, "y", 3,
ulong, "", 3 // <- This line right there
));
}
It that highlighted line really mandatory?
I'm fine with having it optional, in case I'd want to have,
say, a 59 bit padding, but can't the implementation figure it
out on it's own?
The original code has it set that way, why? Perhaps so you are
aware and actually have in place where all the bits are assigned
(even if you aren't using them); Be horrible if you used
accidently 33 bits and it extended to 64 without telling you
(Wouldn't it?).
However, having it fill the size in and ignore the last x bits
wouldn't be too hard to do, I've been wondering if I should
remove it.
