持仓风险度：Rust 与同算法 Python

先验证语义，再测量性能。不预设加速结论，不把算法差异计入语言加速。

结论边界

以下是本机、固定 mock、预热后重复测量的结果。 Python 对照按 Rust 的「稳定排序 + 聚合树」重新实现，不使用飞书原 Python 源码。这不是对所有 pandas/NumPy 实现或所有硬件的速度承诺；小输入可能由转换开销主导。速比 = Python 中位数 / Rust 中位数，小于 1 表示 Rust 更慢。

主结果（中位数，毫秒）

计时范围与公平性

两端共享相同原始输入、输入规范化、七个 float64 指标和 datetime 输出契约。逐场景断言所有列数值一致（rtol/atol 1e-12、NaN 同位）。
E2E 是实际公共调用独立计时，包含输入规范化、计算、输出 DataFrame；Rust 还包含四段 Arrow IPC 转换与 PyO3 调用。
核心 = 已规范化的本语言 DataFrame → 输出 DataFrame：包含字段提取、品种编码、校验（Rust）、稳定排序、树更新、结果物化；不是仅树循环。
Rust 内部 Instant 分别测 IPC 解码、完整核心、IPC 编码；普通公共调用不插入计时器。Python 核心独立计时。
转换合计 = Python IPC 编码 + Rust IPC 解码 + Rust IPC 编码 + Python IPC 解码的每轮分段和；不把 E2E−核心的噪声残差当作转换。
分段来自独立调用，不应精确相加为 E2E。PyO3 调用/返回字节拷贝、计时器等未归入四段转换；native_profile_call 给出整个仪表化边界调用供检查。
固定 seed、同一进程、预热、每轮随机交错顺序、保留全部样本及 min/median/p95。数据生成、正确性断言、导入、编译和 HTML 生成不计时。
这是墙钟耗时，未绑定 CPU、未控制系统负载/温度；少量重复的 P95 只是描述统计，不是置信区间。未测峰值内存或并发吞吐。

实现与正确性

时间必须先升序；品种未出现前为空仓，NaN 沿用历史，跨日不断仓，零表示平仓。同时间同品种最后非缺失值胜出。允许杠杆；空头为零时多空比为 NaN。空输入保留八列，拒绝缺失键和无限权重，保留纳秒与时区。

连续 Vec 聚合树维护总/多/空/净/最大/平方和，更新复杂度 O(log S)，总复杂度 O(N log N + N log S + T)，空间 O(N+S+T)，不创建 T×S 网格。重算父节点避免历史增减累积误差；float64 仍存在舍入与溢出限制。没有 unsafe、fast-math 或并行归约。

测试使用手算预期和独立稠密历史 oracle（每时刻每品种重选历史最后有效记录并用 math.fsum），不只验证两棵树互相一致。覆盖乱序、隔夜、重复、缺失、全空仓、杠杆、纳秒/时区、空输入、错误输入、大仓平仓恢复小仓；具体运行证据见随 PR 提交的 verification.txt。

实现前参考 Rust Book iterator performance、Cargo profiles、PyO3 0.28 performance/parallelism 官方文档；来源及设计取舍见 docs/position_risk.md。
