Re: [Boost-users] Fusion: Structs containing an array

Hi!
I am trying to use boost fusion to build [de]serializer for simple types
(int ...) and structs.
I had success until I tried structures holding arrays.
Example:
struct EntryTable
{
    unsigned int count;
    unsigned int data[4];
};
BOOST_FUSION_ADAPT_STRUCT(
  EntryTable,
  (unsigned int, count)
  (unsigned int, data[4])
)
[...]
...
fusion::vector<unsigned int, unsigned int[4]> f2 = t;  // doesnt work (not
even compile)
[...]
...
What am I doing wrong? Is there a simple way to simple wrap an array using
fusion?
It's infeasible to use C-array here since there's no assignment for such.
Use Boost.Array instead.

Sample code
---------------------
typedef boost::array<unsigned int, 4> array_t;

struct EntryTable
{
    unsigned int count;
    boost::array<unsigned int, 4> data;
};

BOOST_FUSION_ADAPT_STRUCT(
  EntryTable,
  (unsigned int, count)
  (array_t, data)
)
...

EntryTable t;
fusion::vector<unsigned int, array_t> f2 = t;  // now it should work

HTH
