Hello all,

I'm trying to do something like this with fusion:

struct exists_tag {};

template <typename A> struct unary { type_a m_name; };

template <> struct unary { type_b m_name; };

BOOST_FUSION_ADAPT_TPL_STRUCT((A), (unary)(A), (type_a)(m_name)); BOOST_FUSION_ADAPT_TPL_STRUCT((), (unary)(exists_tag), (type_b)(m_name));

I'm not sure if I'm way off here, or if there is some way to accomplish this that I'm just not seeing.

Why do you need to adapt the specialization? If you adapt the main template, fusion can pickup all the specializations just fine. Regards, -- Joel de Guzman http://www.ciere.com http://boost-spirit.com http://www.cycfi.com/
