There exist many C++ JSON libraries, but two are particularly noteworthy for the purpose of comparison: https://rapidjson.org/[RapidJSON], https://nlohmann.github.io/json/[JSON for Modern {cpp}] (referred to herein as nlohmann's JSON, or nlohmann), and https://github.com/lemire/simdjson[SIMD JSON].

C++ 中存在众多 JSON 库，但为了比较的目的，有三个在对比中尤为值得关注：https://rapidjson.org/[RapidJSON]、https://nlohmann.github.io/json/[JSON for Modern {cpp}]（本文中称为 nlohmann's JSON， 或简称 nlohmann）以及https://github.com/lemire/simdjson[SIMD JSON]。
Comparison to nlohmann JSON
与nlohmann JSON的比较
Value Type: https://github.com/nlohmann/json/blob/00cb98a3d170161711ab912ae6acefba31f29f75/include/nlohmann/json.hpp#L165[`nlohmann::basic_json`]

This library adopts a "kitchen sink" approach. It contains a wealth of features, even those with niche uses. Its weakness is that the many template parameters, while allowing for configurability, inhibit the best possible optimizations. The consequence is that the library performs poorly. The ability to configure every aspect of the value type has the paradoxical effect of making it less suitable as a vocabulary type.
该库采用了一种“大而全”（kitchen sink）的设计理念，包含大量功能，甚至涵盖一些使用场景非常小众的特性。其弱点在于：尽管众多模板参数提供了高度可配置性，却阻碍了编译器实现最优的性能优化。其结果是性能表现较差。这种对值类型各方面均可配置的能力，反而使其作为通用类型的适用性降低，形成了一种悖论效应。

{icon_bad} `basic_json` 是一个类模板。各库必须在

模板参数的选择上达成一致，这样才能实现互操作。

将 `BooleanType` 设置为 `bool` 之外的其他类型的使用场景。

声明不必要地将解析和序列化API混杂在一起。

这排除了最重要的一类分配器，即基于本地内存池的实现。
