Detailed Description

Writer 消费的编译格式运行期协议。 / Compiled-format runtime contract consumed by Writer.

A compiled format source always provides Codes(), one contiguous uint8_t byte block terminated in-band by FormatOp::End; ArgumentList(), one field-ordered FormatArgumentInfo array used for runtime argument packing; and Profile(), one compile-time runtime executor profile. Frontends that allow reordered call-site arguments may additionally expose a separate compile-time ArgumentOrder() list or a source-ordered matching list. 编译格式源总会提供三部分：Codes()，即一段在块内用 FormatOp::End 结束的连续 uint8_t 字节块；ArgumentList()，即按字段执行顺序排列、供运行期参数打包使用的 FormatArgumentInfo 数组；以及 Profile()，即一个编译期运行期执行器配置。若某个 前端允许调用点参数重排，还可以额外提供独立的编译期 ArgumentOrder() 索引表或 按源参数顺序排列的匹配元信息表。

每个参数对应的元信息，同时用于编译期类型检查和运行期打包。 / Per-argument metadata used both for compile-time type checking and runtime packing.

pack says how the runtime argument blob stores this argument. rule says which C++ types are accepted at compile time. pack 描述运行期参数字节块里如何存这个参数。 rule 描述编译期允许哪些 C++ 类型匹配这个参数。
