Re: [Boost-users] [Fusion] Assignement from adapted struct to tuple

Hello all, While I managed to assign an adapted structure to a fusion vector, I fail to assign the same structure to a legacy tuple. The doc doesn't mention the assignement operator between two sequences, but I though it would work. Am I missing something ?

First of all, this isn't assignment, it's copy construction. Second, boost::tuple doesn't know anything about Fusion. It doesn't have a constructor that takes an arbitrary Fusion sequence.

#include #include #include

struct my_struct { double a; int b; char c; };

BOOST_FUSION_ADAPT_STRUCT( my_struct, (double, a) (int, b) (char, c));

my_struct src; boost::fusion::vector dest1 = src; //OK boost::tuple dest2 = src; //Fails
