A fast JSON serializing & deserializing library, accelerated by SIMD.
This PR uses the SVE2 HISTSEG instruction to improve performance of ondemand parsing in ARM cpus https://developer.arm.com/documentation/ddi0602/latest/SVE-Instructions/HISTSEG--Count-matching-elements-in-vector-segments- Creating the bitmasks for each structural character is very expensive in ARM due...
## Key Changes CMake Configuration: Added a new build option ENABLE_SVE to enable SVE support with 256-bit vector size. Updated set_arch_flags.cmake to include SVE-specific compile options. SVE-256bit Implementations: Added SVE-specific...
constexpr size_t kExpectMinifyRatio = 18; size_t estimate = node_nums * kExpectMinifyRatio + 64; wb.Reserve(estimate); inc_len = str_len * 6 + 32 + 3; wb.Grow(inc_len); 想问一下，SerializeImpl这个函数里，writerbuffer初始化的长度和Grow的长度是以什么作为考量的，代码里的这些数字代表什么含义呢？最近执行代码的时候发现这里的内存分配感觉有些问题，

场景是：举个例子需要输出{"name":"{"obj":1}"}，而不是  value是一个json字符串，业务场景现在不想解析这个庞大json字符串，而是直接作为一个object透传，之前使用rapidjson库的RawValue操作来实现，现在想迁移sonic-cpp库，支持这种操作吗，还是需要如何实现呢，我看源码里有setRaw接口，但是不开放。
