| <li class=""><strong>快速二进制编码</strong>：快速序列化和优化的二进制协议</li> |
| <li class=""><strong>跨语言</strong>：在 Java、Python、C++、Go、Rust、JavaScript/TypeScript、C#、Swift、Dart、Scala 和 Kotlin 之间无缝序列化和反序列化数据</li> |
| <li class=""><strong>类型安全</strong>：通过基于宏的结构体注册进行编译期类型检查</li> |
| <li class=""><strong>引用跟踪</strong>：自动跟踪共享引用和循环引用</li> |
| <li class=""><strong>Schema 演进</strong>：兼容模式支持独立的 Schema 变更</li> |

| <p>跨语言载荷以及与其他 Fory 实现共享的 Schema 应使用跨语言模式。跨语言模式是 C++ 的默认编码模式；使用该模式的 C++ 示例会显式设置 <code>.xlang(true)</code>，以清楚展示模式选择。</p> |
| <p>仅限 C++ 的通信应使用原生模式。通过 <code>.xlang(false)</code> 选择原生模式，它会让 C++ 对象序列化保持 C++ 原生形式。载荷不会离开 C++ 时，该模式针对 C++ 类型进行了优化，并避免可移植跨语言类型映射的约束。兼容模式默认启用。只有每个读取端和写入端都使用相同的 C++ Schema，并且希望获得更快的序列化和更小的体积时，才设置 <code>.compatible(false)</code>。</p> |
