eos 源码资源限制两个对象

resource_usage_object 实际使用资源

struct resource_usage_object 
{
      id_type id;
      account_name owner; //< owner should not be changed within a chainbase modifier lambda
      
      usage_accumulator        net_usage;
      usage_accumulator        cpu_usage;
      uint64_t                 ram_usage = 0;
}

resource_limits_object 购买的资源

struct resource_limits_object : public chainbase::object<resource_limits_object_type, resource_limits_object> {

      OBJECT_CTOR(resource_limits_object)

      id_type id;
      account_name owner; //< owner should not be changed within a chainbase modifier lambda
      bool pending = false; //< pending should not be changed within a chainbase modifier lambda

      int64_t net_weight = -1;
      int64_t cpu_weight = -1;
      int64_t ram_bytes = -1;

   };
