As far as I can see std.bitmanip only caters for 8, 16, 32, and 64 bit long bitfields.
I worked on/with bitfields in the past, the limit sizes is more or less for natural int types that D supports.
However this limitation is kinda arbitrary, as for simplicity it relies on shifting bits, going larger or any byte size is possible depending on what needs to be stored, but ti's the speed that really takes a penalty when you aren't using native types or you have to do a lot of shifting to get the job done.
What's the layout of what you need? I'll see if i can't make something that would work for you.
Would be better if you can use a object that breaks the parts down and you can actually fully access those parts, then just re-store it into the limited space you want for storage, which then would be faster than bitfields (although not by much)
