Re: [Boost-users] [fusion] memory layout of fusion::vector vs boost::tuple/boost::array

Hi,

I am trying to convert a boost::array into a fusion::vector. reinterpreting the memory from boost::array. It works for tuples but not fusion::vector, why is that. Is there a way to make it work? ( I was hoping that the memory layout is the same to make conversion from one to the other very easy.)

Don't do that. It will *never* be guaranteed to work even if it works now. The memory layout of fusion::vector is an internal implementation detail and can change anytime. Regards, -- Joel de Guzman http://www.boostpro.com http://spirit.sf.net
