2026-05-05 +- **深度脱敏与性能平衡**: + - 引入“混合路径”序列化策略：对基础类型（String, Int, Bool 等）采用高性能手动编码，对复杂类型（Struct, Map, Slice）采用 `cast.ToJSONDesensitizeBytes`。 + - 完美解决嵌套对象、数组内对象的深度脱敏问题，同时将序列化性能维持在极高水平。 +- **基准测试优化**: 相比全量 `cast` 调用，混合路径将异步写入耗时降低了 60% 以上，内存分配减少了 70%。 + ## [1.1.7] - 2026-05-05 - **极致精简与摩擦消除**: - 移除了所有冗余或已弃用的配置项：`Fast`, `KeepKeyCase`, `RegexSensitive`, `SensitiveRule`。 diff --git a/TEST.md b/TEST.md index 596e000..8eaee69 100644 --- a/TEST.md +++ b/TEST.md @@ -5,13 +5,13 @@ -
