Question

I have the following two boost::fusion maps.

namespace bf = boost::fusion;
typedef bf::map<bf::pair<char,float>,bf::pair<int,double>> FusionMap;
typedef bf::result_of::at_key<FusionMap, char>::type localType; // fine

typedef bf::vector<bf::pair<char,float>,bf::pair<int,double>> FusionVec;
typedef bf::result_of::as_map<FusionVec> FusionMap2;
typedef bf::result_of::at_key<FusionMap2, char>::type localType2; // compile error

The first version works where as the second one gives me a compile error. My Compiler is VS2010.
Am I using the as_map function in a wrong way. I assumed that both maps should be identical.

Answer 1

There is a ::type missing at the end of FusionMap2 définition.
