Function ecs_query_next_table 

pub unsafe extern "C" fn ecs_query_next_table(
    iter: *mut ecs_iter_t,
) -> bool

Fast alternative to ecs_query_next that only returns matched tables. This operation only populates the ecs_iter_t::table field. To access the matched components, call ecs_query_populate.

If this operation is used with a query that has inout/out terms, those terms will not be marked dirty unless ecs_query_populate is called.

@param iter The iterator. @returns True if more data is available, false if not.
