Detailed Description

Converter function to convert non-POT types and especially structs to HDF5 types.

Example:

// Struct that is stored in DASH array
struct value_t { double a; int b; };

// Conversion function
auto converter = [](){
  hid_t h5tid = H5Tcreate (H5T_COMPOUND, sizeof(value_t));
  H5Tinsert(h5tid, "a_name", HOFFSET(value_t, a), H5T_NATIVE_DOUBLE);
  H5Tinsert(h5tid, "b_name", HOFFSET(value_t, b), H5T_NATIVE_INT);
  return h5tid;
};

dash::Array<value_t> array_a(1000);
// [...]
// store data
OutputStream os(_filename);
    os << dio::dataset("array_a")
       << dio::type_converter(converter)
       << array_a;

// restore data
dash::Array<value_t> array_b(1000);
InputStream is(_filename);
is >> dio::dataset("array_a")
   >> dio::type_converter(converter)
   >> array_b;
