Hi,
Has anyone used D to work with arbitrary length bitfields with
multiple occurences of a sub-bitfield. I am working with DVB
Sections and EIT packets are defined as bitfields with loops in
them and the header is 112 bits. The loops are handleable with
subfields obviously, assuming you can work out how the
bigendian works on the byte sequence.
As far as I can see std.bitmanip only caters for 8, 16, 32, and
64 bit long bitfields.
Never used it myself, but BitArray with careful handling of
endianess might fit your task.
