API 完全不同 32 | ```cpp 33 | // IceOryx C++ API 34 | iox::popo::Publisher pub({"Service", "Instance", "Event"}); 35 | pub.loan().and_then([](auto& sample) { sample.publish(); }); 36 | ``` 37 | 38 | ```rust 39 | // iceoryx2 Rust API 40 | let node = NodeBuilder::new().create().unwrap(); 41 | let service = node.service_builder("Service").publish_subscribe::().open_or_create().unwrap(); 42 | let publisher = service.publisher_builder().create().unwrap(); 43 | ``` 44 | 45 | ## 解决方案 46 | 47 | ### 方案 1: 使用 JSON/MessagePack 进行跨语言通信 (推荐) 48 | 49 | 通过序列化实现跨语言通信: 50 | 51 | ```cpp 52 | // C++ Publisher 53 | auto json_data = serialize_to_json(market_data); 54 | broadcaster.broadcast(json_data.data(), json_data.size(), ...); 55 | ``` 56 | 57 | ```rust 58 | // Rust Subscriber 59 | let json_data = subscriber.receive().unwrap(); 60 | let market_data: MarketData = deserialize_from_json(&json_data); 61 | ``` 62 | 63 | **优点**: 64 | - ✅ 语言无关 65 | - ✅ 易于调试 66 | - ✅ 向后兼容 67 | 68 | **缺点**: 69 | - ⚠️ 序列化开销 70 | - ⚠️ 失去零拷贝优势 71 | 72 | ### 方案 2: 统一到同一个 IPC 库 73 | 74 | #### 选项 A: 全部使用 IceOryx C++ 75 | - C++: 原生支持 ✅ 76 | - Rust: 通过 bindgen/FFI 绑定 ⚠️ 77 | 78 | #### 选项 B: 全部使用 iceoryx2 79 | - Rust: 原生支持 ✅ 80 | - C++: 通过 iceoryx2-ffi (实验性) ⚠️ 81 | 82 | ### 方案 3: 双栈方案 (当前实现) 83 | 84 | **保持两个独立的 IPC 实现**: 85 | 86 | #### QAULTRA C++ Stack 87 | ``` 88 | Application (C++) 89 | ↓ 90 | DataBroadcaster/DataSubscriber (C++) 91 | ↓ 92 | IceOryx 2.x (C++) 93 | ↓ 94 | Shared Memory 95 | ``` 96 | 97 | #### QARS Rust Stack 98 | ``` 99 | Application (Rust) 100 | ↓ 101 | DataBroadcaster/DataSubscriber (Rust) 102 | ↓ 103 | iceoryx2 0.7.0 (Rust) 104 | ↓ 105 | Shared Memory (独立) 106 | ``` 107 | 108 | **优点**: 109 | - ✅ 每个生态系统内性能最优 110 | - ✅ API 设计完全对齐 111 | - ✅ 独立维护和升级 112 | 113 | **缺点**: 114 | - ❌ 无法直接跨语言通信 115 | 116 | ## 性能对比 117 | 118 | 尽管不能直接通信，但两个实现的性能都很优秀: 119 | 120 | | 指标 | QAULTRA C++ | QARS Rust | 121 | |------|-------------|-----------| 122 | | 单订阅者吞吐量 |

63,291 msg/sec, 7.97 μs avg latency 139 | ``` 140 | 141 | ### QARS Rust IPC 测试 ✅ 142 | ```bash 143 | cd /home/quantaxis/qars2 144 | cargo run --example massive_scale_stress_test --release 145 | 146 | ✅ 500 订阅者 + 100万 ticks 147 | ✅ 1000 订阅者 + 50万 ticks 148 | ✅ 极限吞吐量测试 149 | ``` 150 | 151 | ## 推荐架构 152 | 153 | ### 场景 1: 纯 C++ 项目 154 | 使用 **QAULTRA C++ + IceOryx** 155 | 156 | ```cpp 157 | #include "qaultra/ipc/broadcast_hub.hpp" 158 | 159 | DataBroadcaster::initialize_runtime("my_app"); 160 | DataBroadcaster broadcaster(config, "stream"); 161 | broadcaster.broadcast(data, size, count, type); 162 | ``` 163 | 164 | ### 场景 2: 纯 Rust 项目 165 | 使用 **QARS Rust + iceoryx2** 166 | 167 | ```rust 168 | use qars::qadata::broadcast_hub::DataBroadcaster; 169 | 170 | let broadcaster = DataBroadcaster::new(config); 171 | broadcaster.broadcast("stream", data, count, data_type)?; 172 | ``` 173 | 174 | ### 场景 3: 混合项目 (C++ + Rust) 175 | 176 | **方案 A: 使用 HTTP/gRPC 作为桥接** 177 | ``` 178 | C++ App → IceOryx → C++ Gateway → HTTP/gRPC → Rust Gateway → iceoryx2 → Rust App 179 | ``` 180 | 181 | **方案 B: 使用共享数据库** 182 | ``` 183 | C++ App → IceOryx → C++ Writer → Database ← Rust Reader ← iceoryx2 ← Rust App 184 | ``` 185 | 186 | **方案 C: 使用文件/管道** 187 | ``` 188 | C++ App → IceOryx → C++ Writer → Named Pipe → Rust Reader → iceoryx2 → Rust App 189 | ``` 190 | 191 | ## 未来展望 192 | 193 | ### iceoryx2 C++ 绑定 194 | 195 | iceoryx2 项目有 C++ FFI 绑定，但存在内核版本限制: 196 | - https://github.com/eclipse-iceoryx/iceoryx2 197 | - `iceoryx2-cxx` 完整的 C++ 绑定 198 | - ⚠️ **需要 Linux 5.11+ 内核** (epoll_pwait2) 199 | - 当前系统: Linux 5.4.0 ❌ 200 | 201 | **编译错误**: 202 | ``` 203 | error[E0425]: cannot find function `epoll_pwait2` in module `crate::internal` 204 | ``` 205 | 206 | **解决方案**: 207 | 1. 升级内核到 5.11+ (需要系统管理员权限) 208 | 2. 等待 iceoryx2 改进内核兼容性 209 | 3. 使用当前双栈方案 + 桥接 210 | 211 | ### IceOryx Rust 绑定 212 | 213 | 或者，为 IceOryx C++ 创建 Rust 绑定: 214 | - 使用 `bindgen` 生成 Rust FFI 215 | - 包装为安全的 Rust API 216 | - QARS Rust 可选支持 IceOryx 217 | 218 | ## 总结 219 | 220 | **当前状态**: ⚠️ C++/Rust 直接通信 **不支持** 221 | 222 | **原因**: IceOryx (C++) 和 iceoryx2 (Rust) 是两个独立的、不兼容的 IPC 实现 223 | 224 | **解决方案**: 225 | 1. ✅ **推荐**: 保持双栈，使用 JSON/MessagePack 进行跨语言通信 226 | 2. ✅ 等待 iceoryx2 C++ 绑定成熟 227 | 3. ✅ 在同一语言生态内使用零拷贝 IPC 228 | 229 | **性能**: 两个实现在各自生态内都达到了**生产级性能** 230 | 231 | --- 232 | 233 | **文档版本**: 1.0.0 234 | **创建时间**: 2025-10-01 235 | **状态**: QAULTRA C++ IPC 实现完成并测试通过 ✅ 236 | -------------------------------------------------------------------------------- /docs/unified_system_summary.md:

#include "qaultra/account/unified_account.hpp" 146 | 147 | // 创建账户 148 | UnifiedAccount account("test_account", "", "", 1000000.0); 149 | 150 | // 股票交易 151 | std::string order_id1 = account.buy("000001.XSHE", 1000, 10.0); 152 | std::string order_id2 = account.sell("000001.XSHE", 500, 11.0); 153 | 154 | // 期货交易 155 | std::string order_id3 = account.buy_open("IF2401", 10, 4000.0);

-------------------------------------------------------------------------------- /docs/DUAL_STACK_IPC.md: -------------------------------------------------------------------------------- 1 | # Dual-Stack IPC Architecture 2 | 3 | QAULTRA-CPP now supports **two independent IPC implementations**: 4 | 5 | 1. **IceOryx (v1)** - Eclipse Foundation's C++ IPC middleware 6 | 2. **iceoryx2 (v2)** - Rust-based rewrite with C++/Rust interoperability 7 | 8 | ## Why Dual-Stack? 9 | 10 | ### IceOryx (v1) Advantages 11 | - **Mature and stable** - Production-tested in automotive industry 12 | - **Pure C++** - Native C++ API with no FFI overhead 13 | - **RouDi daemon** - Centralized service discovery and management 14 | - **Performance** - Proven zero-copy shared memory IPC 15 | 16 | ### iceoryx2 (v2) Advantages 17 | - **Cross-language** - Seamless C++/Rust interoperability 18 | - **Modern architecture** - Distributed service discovery, no daemon required 19 | - **Memory safety** - Rust implementation reduces bugs 20 | - **Future-proof** - Active development, modern design patterns 21 | 22 | ## Architecture 23 | 24 | ``` 25 | qaultra::ipc 26 | ├── v1 (IceOryx) 27 | │ ├── DataBroadcaster 28 | │ ├── DataSubscriber 29 | │ └── BroadcastManager 30 | └── v2 (iceoryx2) 31 | ├── DataBroadcaster 32 | ├── DataSubscriber 33 | └── BroadcastManager 34 | ``` 35 | 36 | ## API Compatibility 37 | 38 | Both versions provide **identical** high-level APIs: 39 | 40 | ```cpp 41 | // V1 - IceOryx 42 | #include "qaultra/ipc/broadcast_hub_v1.hpp" 43 | using namespace qaultra::ipc::v1; 44 | 45 | // V2 - iceoryx2 46 | #include "qaultra/ipc/broadcast_hub_v2.hpp" 47 | using namespace qaultra::ipc::v2; 48 | 49 | // Both share the same interface 50 | DataBroadcaster::initialize_runtime("myapp"); // V1 only 51 | auto broadcaster = DataBroadcaster(config, "stream"); 52 | broadcaster.broadcast(data, size, count, type); 53 | ``` 54 | 55 | ## Usage Examples 56 | 57 | ### V1 - IceOryx (C++ to C++) 58 | 59 | ```cpp 60 | #include "qaultra/ipc/broadcast_hub_v1.hpp" 61 | 62 | using namespace qaultra::ipc::v1; 63 | 64 | // Start RouDi daemon first: 65 | // $ /home/quantaxis/iceoryx/build/install/bin/iox-roudi 66 | 67 | int main() { 68 | DataBroadcaster::initialize_runtime("publisher"); 69 | 70 | BroadcastConfig config; 71 | config.service_name = "MarketData"; 72 | 73 | DataBroadcaster broadcaster(config, "ticks"); 74 | 75 | uint8_t data[1024]; 76 | broadcaster.broadcast(data, 1024, 100, MarketDataType::Tick); 77 | } 78 | ``` 79 | 80 | ### V2 - iceoryx2 (C++ to C++ or C++ to Rust) 81 | 82 | ```cpp 83 | #include "qaultra/ipc/broadcast_hub_v2.hpp" 84 | 85 | using namespace qaultra::ipc::v2; 86 | 87 | // No daemon required! 88 | 89 | int main() { 90 | BroadcastConfig config; 91 | config.service_name = "MarketData"; 92 | 93 | DataBroadcaster broadcaster(config, "ticks"); 94 | 95 | uint8_t data[1024]; 96 | broadcaster.broadcast(data, 1024, 100, MarketDataType::Tick); 97 | } 98 | ``` 99 | 100 | ### V2 - Cross-Language (C++ Publisher + Rust Subscriber) 101 | 102 | **C++ Publisher:** 103 | ```cpp 104 | #include "qaultra/ipc/broadcast_hub_v2.hpp" 105 | using namespace qaultra::ipc::v2; 106 | 107 | DataBroadcaster broadcaster(config, "market_data"); 108 | broadcaster.broadcast(data, size, count, MarketDataType::Tick); 109 | ``` 110 | 111 | **Rust Subscriber:** 112 | ```rust 113 | use iceoryx2::prelude::*; 114 | 115 | let node = NodeBuilder::new().create::().unwrap(); 116 | let service = node.service_builder(&"market_data".try_into().unwrap()) 117 | .publish_subscribe::() 118 | .open_or_create() 119 | .unwrap(); 120 | 121 | let subscriber = service.subscriber_builder().create().unwrap(); 122 | 123 | while let Some(sample) = subscriber.receive().unwrap() { 124 | println!("Received: {:?}", sample.payload()); 125 | } 126 | ``` 127 | 128 | ## Build Configuration 129 | 130 | Both versions can be enabled/disabled independently: 131 | 132 | ```cmake 133 | # CMakeLists.txt 134 | option(QAULTRA_USE_ICEORYX "Use IceOryx for zero-copy IPC" ON)

access) 160 | 161 | ## Dependencies 162 | 163 | ### IceOryx V1 164 | ``` 165 | /home/quantaxis/iceoryx/build/install/ 166 | ├── lib/libiceoryx_posh.a 167 | ├── lib/libiceoryx_hoofs.a 168 | └── bin/iox-roudi (daemon) 169 | ``` 170 | 171 | ### iceoryx2 V2 172 | ``` 173 | /home/quantaxis/iceoryx2/build/ 174 | ├── iceoryx2-cxx/libiceoryx2_cxx.a (C++ bindings) 175 | └── rust/native/release/libiceoryx2_ffi_c.a (Rust FFI layer) 176 | ``` 177 | 178 | ## Runtime Requirements 179 | 180 | ### V1 - IceOryx 181 | **Required**: RouDi daemon must be running 182 | ```bash 183 | /home/quantaxis/iceoryx/build/install/bin/iox-roudi & 184 | ``` 185 | 186 | ### V2 - iceoryx2 187 | **No daemon required** - fully distributed architecture 188 | 189 | ## When to Use Which? 190 | 191 | ### Use IceOryx V1 when: 192 | - ✅ Pure C++ application 193 | - ✅ Mature, production-tested solution needed 194 | - ✅ Automotive-grade reliability required 195 | - ✅ Centralized management preferred 196 | 197 | ### Use iceoryx2 V2 when: 198 | - ✅ Cross-language communication needed (C++/Rust) 199 | - ✅ No daemon overhead acceptable 200 | - ✅ Modern distributed architecture preferred 201 | - ✅ Future integration with QARS Rust code 202 | 203 | ## Migration Path 204 | 205 | Applications can: 206 | 1. **Start with V1** for immediate stability 207 | 2. **Migrate to V2** when cross-language features needed 208 | 3. **Run both** during transition period (different namespaces) 209 | 210 | ## Limitations 211 | 212 | ### V1 Limitations 213 | - ❌ No cross-language support (C++ only) 214 | - ❌ Requires RouDi daemon 215 | - ❌ Single-point-of-failure (daemon) 216 | 217 | ### V2 Limitations 218 | - ⚠️ Newer, less battle-tested 219 | - ⚠️ Small FFI overhead for C++ bindings 220 | - ⚠️ Requires Rust toolchain for building 221 | 222 | ## Future Work 223 | 224 | - [ ] Performance benchmarks V1 vs V2 225 | - [ ] Cross-language integration tests 226 | - [ ] Python bindings via V2 227 | - [ ] Unified abstraction layer (auto-select V1/V2) 228 | 229 | ## Summary 230 | 231 | The dual-stack architecture provides **flexibility** and **future-proofing**: 232 | - Use **V1** for immediate C++ needs 233 | - Use **V2** for C++/Rust interoperability 234 | - Both share common data structures (`ZeroCopyMarketBlock`) 235 | - Seamless migration path as requirements evolve 236 |
