## Data Fields
Eina_Value | value
| The race result.
unsigned int | index
| The future index that won the race.

## Detailed Description

The struct that is used to store the race result.

When using eina_promise_race_array() and friends, the future result will be reported as a struct. The values can be obtained using eina_value_struct_get() or one could access the struct directly such as this example:

static Eina_Value
_race_cb(const void *data EINA_UNUSED, const Eina_Value v)
{
//code...
Eina_Value_Struct st;
Eina_Future_Race_Result *rr;
eina_value_get(v, &st);
rr = st.memory;
printf("Winning future index: %u\n", rr->index);
//more code..
return v;
}
