[Boost-users] member traits

I am still on my adventure to implement a library for manipulating  
bits for device drivers.  I want to be able to define a struct or a  
class that has the same layout as the hardware registers and also  
define bits for the registers.  I want to have compile time checking  
to make sure that I use the bit definitions with the proper  
register.  Underneath will be something maybe called "access" classes  
that would pull the data from the hardware device on the bus or write  
it back out.  Sometimes that is just a simple pointer dereference but  
other times it is a kernel service call.

I've worked on this for a couple of weeks (off and on) and I have  
something that is kinda working but does not do everything that I need.

All that to lead up to this question:  from what I've determined so  
far, all this boils down to giving what is equivalent  to traits to  
members of a class or struct.  Then I can give traits to the bit  
fields and have a compile time assert to make sure that the traits  
match.

My only thought so far is to give each member its own unique type and  
then assign traits to those types.  I am wondering if that seems like  
a viable path or if there are alternate (better?) ways.

Thank you,
Perry
